What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does the term 'exponent' mean?

Back

An exponent is a number that indicates how many times to multiply the base number by itself. For example, in 4², 2 is the exponent, meaning 4 is multiplied by itself 2 times (4 x 4).

Calculate: 3 + 5 x 2

Back

13 (First, multiply 5 x 2 = 10, then add 3 = 13).

Front

What is the result of 10 - 3 + 2?

Back

9 (First, subtract 3 from 10 = 7, then add 2 = 9).

Front

Which operation should be performed first in the expression 6 + 2 x 3?

Back

Multiplication should be performed first. So, 2 x 3 = 6, then add 6 = 12.

What is the value of 5^3?

Back

125 (5 x 5 x 5 = 125).

Front

Evaluate: 8 + (3 x 2) - 4

Back

10 (First, calculate inside the parentheses: 3 x 2 = 6, then 8 + 6 - 4 = 10).

Front

What does PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

Calculate: 12 ÷ 4 + 5

Back

8 (First, divide 12 by 4 = 3, then add 5 = 8).

Front

What is the equivalent of 2^4?

Back

16 (2 x 2 x 2 x 2 = 16).
