Some SAT Math questions are tricky because of the vocabulary used. Here are four terms that you should get to know. Memorize them and remember to underline them when you see them in practice problems. This should help reduce careless errors.

Factors: Numbers that divide evenly into a number, ie without a remainder. For example, the factors of 12 are 12, 6, 4, 3, 2 and 1.

Multiples: All the numbers that can be divided by a certain number. For example, the multiples of 2 are 2, 4, 6, 8, etc.

Prime Number: A number whose only factors are 1 and itself. For example, 2, 3, 5 and 7. Don’t be tricked! The number 1 is NOT a prime number, and the number 2 is the ONLY even prime number.

Units Digit: A fancy schmancy way to say the “ones” digit in a number; for example, the 4 in 534.
