What is the Order of Operations in mathematics?

Back

The Order of Operations is a set of rules that dictates the sequence in which calculations are performed in a mathematical expression. 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 'expanded form' mean in mathematics?

Back

Expanded form is a way of writing numbers to show the value of each digit. For example, 4^6 in expanded form is 4 x 4 x 4 x 4 x 4 x 4.

How do you solve an expression with both addition and multiplication?

Back

According to the Order of Operations, you should perform multiplication before addition. For example, in the expression 4 + 2 x 8, you first calculate 2 x 8, which equals 16, and then add 4, resulting in 20.
