What is the order of operations in mathematics?

Back

The order of operations is a set of rules that dictates the sequence in which operations should be performed in a mathematical expression: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often remembered by the acronym PEMDAS.

How do you add two numbers in a numeric expression?

Back

To add two numbers in a numeric expression, simply combine their values using the addition operation (+). For example, to add 3 and 11, you calculate 3 + 11 = 14.

What does it mean to divide a sum by a number?

Back

Dividing a sum by a number means to take the result of the addition and split it into equal parts. For example, if you add 3 and 11 to get 14, and then divide by 2, you calculate 14 ÷ 2 = 7.

What is the difference between addition and multiplication in numeric expressions?

Back

Addition combines values to find a total, while multiplication finds the total of one number added to itself a certain number of times. For example, 3 + 2 = 5 (addition) and 3 × 2 = 6 (multiplication).

How do you express 'more than' in a numeric expression?

Back

'More than' indicates addition in a numeric expression. For example, '16 more than the quotient of 15 and 3' can be expressed as (15 ÷ 3) + 16.

Front

What does 'the difference between two numbers' mean in a numeric expression?

Back

'The difference between two numbers' refers to the result of subtracting one number from another. For example, the difference between 12 and 7 is expressed as 12 - 7.

Front

How do you multiply a sum by a number in a numeric expression?

Back

To multiply a sum by a number, first calculate the sum, then multiply the result by the number. For example, to multiply the sum of 45 and 11 by 2, calculate (45 + 11) × 2.
