Order of operations

Front

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 common acronym is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

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).

Solve: 3 + 4 x 6 - 4

Back

First, perform multiplication: 4 x 6 = 24. Then, 3 + 24 - 4 = 23.

What is the first step in solving 6 x 7 + (9 - 3) + 2?

Back

The first step is to solve the expression in parentheses: (9 - 3) = 6.

Front

Solve: 15 x 19 + 18 ÷ 6

Back

First, perform the division: 18 ÷ 6 = 3. Then, 15 x 19 = 285. Finally, 285 + 3 = 288.

Front

What is the result of 7 x (7 - 4) ÷ 3?

Back

First, solve the expression in parentheses: (7 - 4) = 3. Then, 7 x 3 = 21. Finally, 21 ÷ 3 = 7.

Front

What operation should be performed first in the expression 5 x (6 - 3)?

Back

The first operation is to solve the expression in parentheses: (6 - 3) = 3.

Front

What is the result of 8 + 2 x 5?

Back

First, perform the multiplication: 2 x 5 = 10. Then, 8 + 10 = 18.

Front

What is the importance of parentheses in order of operations?

Back

Parentheses indicate which operations should be performed first, overriding the usual order of operations.

Front

If an expression has both multiplication and addition, which should be done first?

Back

Multiplication should be done first, according to the order of operations.
