"Number sentence" is the term that's used in K-5-level math teaching in countries, such as the U.S., Canada, the UK, New Zealand, South Africa, and Australia. Here are some examples of number sentences: Addition number sentence: 7 + 5 = 12 Subtraction number sentence: 44 – 10 = 34 Multiplication number sentence: 5 x 4 = 20

When should we use multiplication sentences? We use these sentences when the problem has items in equal quantity in each row or column. We use addition sentence (addition of each row together) when you have one item in the first row, two in the second one, three in the fourth. The expression will be like this 1 + 2 + 3 + 4 = 6.
