Mathematics MCQs

Division and multiplication have equal priority and are performed left to right.
So 48 ÷ 6 = 8, and 8 × 3 = 24.

Multiplication is performed before addition.
Thus, 3 × 4 = 12 and 5 + 12 = 17.

The operation inside parentheses is completed first.
Then 12 ÷ 3 = 4.

Additive inverses sum to zero.
Since 13 + (-13) = 0, the inverse is -13.

The multiplicative inverse of a nonzero fraction is its reciprocal.
Interchanging numerator and denominator gives 7/5.

A composite number has more than two positive factors.
The number 4 has factors 1, 2, and 4.

17 is divisible only by 1 and 17, so it is a prime number.
