1. Read the text about two arithmetical operations and do the exercises that follow it Basic arithmetical operations. (Addition & subtraction)

In spoken English, 2 + 3 = 5 is, ‘Two plus two equals five’ or ‘Two plus three is equal to five’ or ‘Two plus three is five’ or ‘Two increased by three equals five’. This arithmetical operation is called addition. The result of this operation is called the sum. Thus, if two is added to three, the sum is five.

In spoken English, 5 – 3 = 2 is, ‘Five minus three equals two’ or ‘Five minus three is equal to two’ or ‘Five minus three is two’ or ‘Five decreased by three equals two’. This arithmetical operation is called subtraction. The result of this operation is called the difference. Thus, if three is subtracted from five, the difference is two.
