Order of Operations with Integers

Front

What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. 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 PEMDAS stand for?

Back

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

Front

What is the first step in the Order of Operations?

Back

The first step is to solve expressions inside Parentheses.

Front

How do you handle multiplication and division in the Order of Operations?

Back

Multiplication and division are performed from left to right, as they appear in the expression.

Front

How do you handle addition and subtraction in the Order of Operations?

Back

Addition and subtraction are performed from left to right, as they appear in the expression.

Front

What is the result of 5 - 3 + 2?

Back

The correct result is 4, because you should subtract first: 5 - 3 = 2, then add 2.

Front

What is the result of (-5) - (-3) x (-4)?

Back

The result is -17. First, calculate the multiplication: (-3) x (-4) = 12, then do (-5) - 12 = -17.

Is 2 ∗ 3 + 10 ÷ 2 = 8 true or false?

Back

False. The correct calculation is 2 * 3 = 6, then 10 ÷ 2 = 5, and 6 + 5 = 11.

Front

What is the result of 3 + 27 ÷ (-3)?

Back

The result is -6. First, calculate 27 ÷ (-3) = -9, then 3 + (-9) = -6.

Front

What is the result of -4(-1 + 8)?

Back

The result is -28. First, calculate (-1 + 8) = 7, then -4 * 7 = -28.
