Answer: Hey Mate!
To expand a bracket means to multiply each term in the bracket by the expression outside the bracket. For example, in the expression 3 ( m + 7 ) , multiply both. 3 ( m + 7 ) = 3 × m + 3 × 7 = 3 m + 21 .

For example, in the expression 3 ( m + 7 ) , multiply both. 3 ( m + 7 ) = 3 × m + 3 × 7 = 3 m + 21 . You first solve the operations within the bracket. This is called “opening the bracket'. Then you move on to division, after which you perform multiplication if the equation requires it from left to right. And finally, you add the numbers and lastly perform the subtraction.
