6.7A Order of Operations

Front

What is the Order of Operations?

Back

A set of rules that determines the correct sequence to evaluate a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

What does PEMDAS stand for?

Back

PEMDAS is an acronym for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction, which helps remember the order of operations.

Front

What is the first step in solving the expression 50 - 16 ÷ 2 × (12 + 4)?

Back

The first step is to solve the expression inside the parentheses: (12 + 4) = 16.

Front

In the expression (12 + 10) ÷ 10 · 14 - 6, which operation is performed first?

Back

Addition (inside the parentheses) is performed first.

Front

What is the result of the expression 6^3 - 10 ÷ 5?

Back

The result is 214.

Front

Back

The value is 15.

Front

When simplifying the expression 7 + 41 ÷ 2 - 15, what is the second step?

Back

The second step is to perform the division: 41 ÷ 2 = 20.5.

Front

What operation comes after division in the order of operations?

Back

Multiplication comes after division, and they are performed from left to right.

Front

Back

The result is 50 - 8 × 16 = 50 - 128 = -78.

Front

In the expression 6^3, what does the exponent represent?

Back

The exponent represents how many times the base (6) is multiplied by itself: 6 × 6 × 6 = 216.
