Order of Operations with Exponents

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 acronym PEMDAS is often used to remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does the term 'exponent' refer to in mathematics?

Back

An exponent refers to the number of times a base is multiplied by itself. For example, in 2^3, 2 is the base and 3 is the exponent, meaning 2 is multiplied by itself 3 times (2 x 2 x 2).

What is the result of 42 ÷ (15 - 2^3)?

Back

First, calculate 2^3 which is 8. Then, simplify the expression inside the parentheses: 15 - 8 = 7. Finally, divide: 42 ÷ 7 = 6.
