Yes, doctors indeed require math to perform various tasks ranging from calculating medication doses to interpreting medical research data. In fact, math is an integral part of the medical field and is considered as one of the core subject areas in medical education.
According to Dr. Christopher Moriates, an Assistant Dean for Healthcare Value at Dell Medical School, “Math is essential to the practice of medicine. Doctors use math to determine the proper dosage of medication, monitor health statistics and make diagnoses. Even more importantly, they use it to weigh the risks and benefits of potential treatments and communicate these to their patients.”
Here are some interesting facts on the importance of math for doctors:

Physicians often use complex mathematical models to diagnose and treat patients with chronic health conditions, such as diabetes and heart disease.

Math plays a vital role in understanding the pharmacokinetics of various drugs, which helps doctors to determine the appropriate doses for patients.

Medical students are required to take courses in biostatistics and medical informatics, which teach them how to interpret medical data and conduct research studies.

Surgeons use math to plan and perform surgical procedures, such as determining the correct angle and depth for an incision.

Medical researchers use sophisticated statistical methods to analyze large datasets and draw conclusions about the effectiveness of different treatments.
To emphasize the importance of math in medicine, here is a table that illustrates some of the ways doctors use math:
Task  Math Skill Required 

Calculating medication doses  Basic math (addition, subtraction, multiplication, division) 
Monitoring vital signs  Basic math (percentages, ratios) 
Interpreting medical test data  Statistics, probability, calculus 
Conducting medical research  Biostatistics, data analysis, hypothesis testing, experimental design, modeling 
Planning surgical procedures  Trigonometry, geometry, calculus 
In conclusion, doctors absolutely need math to perform their jobs accurately and effectively. Without math, it would be impossible to provide proper healthcare and make informed decisions about patient treatment. As Dr. Moriates notes, “Math may not seem like a glamorous part of medicine, but it’s essential to ensuring that patients receive the best care possible.”
Answer to your inquiry in video form
The video “How Do Doctors Use Math?” explains the various ways doctors utilize math in their profession. Doctors take measurements like weight, blood pressure, and heart rate to help diagnose patients and analyze the data collected to create graphs and determine percentages and ratios to see if the patient’s levels are balanced. They also use business math to keep their practice running smoothly, calculating revenue and cost to ensure financial stability.

People always think that biology and chemistry are important for doctors, nurses, midwives, scientists, and all the other people involved in medicine, but in fact, math is also vital.

According to the Math Central website, doctors also use math "when drawing up statistical graphs of epidemics or success rates of treatments." Math skills also are important when analyzing Xrays and CAT scans.
Students who want to become doctors should take all available math courses in high school. In chronological order, most high schools and many colleges offer students courses in prealgebra, algebra 1, algebra 2 and trigonometry or precalculus. Each of these courses require students to have a passing grade in the previous courses.
Mathematics plays a vital role in medicine. Since people’s lives are involved, it is crucial that nurses and doctors be really accurate with their mathematical calculations. Numbers will give information to doctors, nurses, as well as patients. Numbers are very essential within the medical area.
Two semesters of calculus are required for medical school. More time will have to be devoted to math classes if you need to take prerequisite courses or an optional semester of statistics. You will take math classes from one to two and a half years, assuming that you are taking one math class per semester.
The more immediate reasons that math is useful to future physicians are evident in the premed curriculum itself. First, many medical schools require either calculus or statistics (or both) to be considered for admission.
