Math word problems

A word problem is a mathematical question that is presented in the form of a story or real-life scenario, requiring the reader to extract the necessary information to solve it.

To find the total amount when adding, you combine the values together. For example, if you have 3 apples and get 2 more, you have 3 + 2 = 5 apples.

Subtracting means to take away a number from another. For example, if you have 10 candies and eat 3, you have 10 - 3 = 7 candies left.

The first step is to read the problem carefully and identify what is being asked.

To determine the change in temperature, subtract the lower temperature from the higher temperature. For example, if it was 80 degrees and then 50 degrees, the change is 80 - 50 = 30 degrees.

'Each' refers to every individual item in a group. For example, if there are 4 bags and each bag has 5 apples, there are 4 x 5 = 20 apples in total.

To divide items equally, you take the total number of items and divide it by the number of people. For example, if there are 12 cookies and 4 people, each person gets 12 ÷ 4 = 3 cookies.

Multiplication is used to find the total when you have groups of the same size. For example, if there are 5 packs of pencils with 8 pencils each, the total is 5 x 8 = 40 pencils.

Finding the total cost means adding up the prices of all items purchased. For example, if one chair costs $5 and you buy 4 chairs, the total cost is 4 x 5 = $20.

Key words that indicate addition include 'total', 'combined', 'together', and 'in all'.
