Math in Medicine

Doctors and nurses use math every single day. They measure medicine doses, check heart rates, and read test results. Getting the math right is very important for keeping people healthy.

Medicine Doses

The right dose of medicine depends on a person's weight and age. A child gets a smaller dose than an adult. Doctors calculate the exact amount so it works safely.

Pharmacists also use math to mix medicines. They measure liquids in milliliters and solids in milligrams. Exact math is a must.

Tests and Measurements

When you visit the doctor, they measure your height, weight, and temperature. These numbers help the doctor know if you are healthy.

Blood tests give numbers too. Doctors compare your numbers to normal ranges. If a number is too high or too low, it might mean something needs attention.

Fun Facts

• A normal resting heart rate for kids is between 70 and 100 beats per minute.
• Body temperature is usually about 98.6 degrees Fahrenheit.
• Surgeons use exact measurements so they know precisely where to operate.
