No, law students do not need math but it can help certain practice areas like bankruptcy and tax law!

Even though law schools do not explicitly teach math as part of their curriculum and the LSAT (the test that must be taken to practice law legally) does not contain a math element, mathematical knowledge is highly beneficial in law. Mathematics is an excellent major by professional graduate schools in law, medicine, and business. It develops critical thinking skills and the capacity to operate in a problem-solving situation.

Furthermore, students majoring in mathematics obtain significantly higher marks on admission tests for professional and graduate schools than students majoring in most other fields.

A four-year college degree in an area such as mathematics, three years of school of law, and passing a written bar exam are usually required to become a lawyer. Most law schools have intense competition for admission. Physics and math majors outscore all other humanities majors on the LSAT(Law School Admission Test). 

Legal decision-making is affected by poor math skills

According to Jessica Bregant and Arden Rowell’s research, there is a “very substantial connection” between law students’ quality legal analysis and math skills. They imply that legal analysis – and thus legal advice – may vary depending on a lawyer’s basic math skills.

The study reveals that mathematics is more important to lawyers than most people know, and for different reasons said “Rowell, who is a law professor and the Marie L. Corman and Richard W. Scholar at the University of Illinois. “People are only now beginning to notice that judges and lawyers who are poor at math can make mistakes that cause people’s lives to be destroyed.

Because law schools haven’t typically concentrated on mathematics when selecting students, this implicates mathematics as an overlooked but potentially vital part of legal training.”

According to Rowell, the research implies that the benefit of math skills doesn’t stop there, who co-wrote the paper with Bregant, a research fellow at the University of Illinois College of Law.

Even if lawyers don’t make visible math errors, their law knowledge may be completely different depending on their math skills. “In other words, clients may not receive the same result in identical cases simply because the attorney they appoint – or the judge they face – has a high or low math skills.”

Currently, most law schools place a low priority on mathematical ability. 

“In reality, students with mathematical or science backgrounds before they started law school are at a disadvantage when it comes to qualifying into a school of law,” she said. “Their research indicates that this is a risky system.”

Clients should also learn to pay attention to their lawyer’s math abilities. We were able to anticipate how an attorney would answer legal questions just by asking them three simple math questions, raising questions about the reliability and constancy of legal decision-making.”

This is the first empirical investigation of the impact of mathematics on legal decision-making.

“Based on this study, it looks like there is a difference in how law students analyze legal problems based on their math skills.” That said, it’s not known which group is doing a better job at legal analysis – the ones who are good at math or those who are bad at math. It’s not known yet whether people who are bad at math are worse at law.”

Lawyers make various decisions, and many of them require predicting the outcomes of other people’s decisions. 

“For example, if an issue arises about whether a client would be judged negligent if they fail to take a measure, a lawyer listening to the facts, in that case, must consider not only the law but also how lawyers and judges make conclusions about the law.

As a result, persons with inadequate mathematics may better forecast everyone else’s decisions. 

“If judges have low mathematical skills as well, it’s possible that many lawyers who are not as excellent at arithmetic are the better predictions. However, before we can say that, a lot of research is needed on mathematical ability and legal decision-making.

People with weak analytical skills have been found to have a variety of decision-making challenges, including being more susceptible to cognitive bias and being “fooled or misled” by the way things are portrayed.

In terms of review evidence, criminal law – statistics are significant. A criminal attorney will likely rely on expert witnesses in many cases, but it’s vital to recognize evidence that depends on probability and other mathematical principles. I believe logic and common sense are linked in some way. Both of these skills are essential in legal practice. Basic proficiency in mathematics and logical reasoning to develop proofs can be valuable in constructing a solid case and reviewing documents. It would also aid in the discovery of logical faults in opposing briefs.

When the data were compared to legal analyses conducted by members of the general public who had no legal experience, the researchers discovered that lawyers, regardless of their mathematical level, were less subject to cognitive bias. It was speculated that law students could be more prone to biases and framing effects, either due to their legal education or because lawyers are naturally skeptical.

Someone who chooses to become a good lawyer also enjoys reading the fine print and natural wonders, “What is hidden?” “What’s the catch?” enquires the narrator. “As a result, that way of thinking could be a form of cognitive bias prevention.” 

However, a lawyer’s ability to foresee outcomes isn’t enough to make or break a career.

To fill out timesheets, charge clients, and manage their company expenses, all newly certified law school graduates who proceed to work for law firms need essential math expertise.

Real estate, contracts, securities trusts and estates, taxation, and bankruptcy are legal areas where business mathematics knowledge is required. 

A law student interested in entering legal specializations involving science, such as the trademark area of health care law or property law, should consider taking two semesters of introduction to calculus. It is often required to know scientific subjects related to these fields of law, such as biology and physics.

Although a lawyer may employ a financial or accounting professional to help in certain situations, basic knowledge can help a lawyer take complete control of a case and make the best decisions possible. Registering for business math classes and introductory financial accounting will help lawyers interpret financial data, as recommended by the American Bar Association.

Law School

According to a Social Science Research Network study, students focusing on pure mathematics or physics scored the highest on the Law School Admission Test (LSAT). According to findings, math-inclined legal students may profit in two ways throughout law school.

Mathematical computations are required in some disciplines, such as tax law. Second, law institutions teach students “legal reasoning,” a step-by-step approach of critical analysis of common legal issues that students with a math background may find simpler to comprehend than students with a humanities background.

Law schools have approved students with a wide range of undergraduate majors. Still, an American Bar Association (ABA) essay titled “Preparing for Law School” now advises undergraduates considering law school to develop “simple mathematical and businesses come, such as a knowledge of fundamental pre-calculus mathematics and the ability to interpret financial data.”

How lawyers and law students use mathematical skills can help future lawyers decide which math courses they should take.

Legal Practice 

English, economics, history, political science, business administration, and rhetoric are law school applicants’ most common undergraduate majors.

The American Bar Association’s suggestion that many lawyers take more college math coursework reflects a steady movement in legal practice that started in the 1970s toward greater use of statistics and other types of maths in trial preparation and other elements of legal practice. 

Required math courses for undergraduates 

There is no unanimous agreement on the types of math classes that prospective lawyers should study as undergraduates. According to the ABA’s pre-calculus mathematics recommendations and historical advice from math majors who became lawyers, aspiring lawyers should take at least undergraduate courses in Finite Mathematics, Trigonometry, Calculus I and II, Geometry, and College Algebra.

When is math used?

In their daily business activities, attorneys use maths abilities, including logic and problem-solving. Attorneys in court must prove their knowledge of the case in steps, similar to a math problem. Patent lawyers also apply math in their cases to scientifically show or deny the validity of a patent.


To operate well in legal fields such as health care law or patent law, lawyers require a basic understanding of pure mathematics such as statistics and calculus. Many court cases rely on statistics to justify factual points, so attorneys who specialize in litigation often need to understand statistics.
