First write down '5 + b'

NB in algebra you must always show the plus sign.

Next put the '5 + b' in brackets. ; (5 + b)

When you require half of this value , you are dividing by '2' . So it is written as

(5 + b)/2

NNB the 'slash sign ; '/' represents divide in algebra.

NNNB Do not write 5 + b/2 , because this means the 'whole number '5' is added to half of 'b' only/ You must use the brackets.

e.g.

Let 'b' = 7

So '5 + 7' = ( 5 + 7) =>

( 5 + 7) / 2

#Remember the rule in maths ; you do inside the brackets first.

Hence ( 5 + 7) / 2 = 12 /2 Then divide 12/2 = 6 The Answer.

For the other method you will a completely different answer.

5 + 7/2 = 5 + 3.5 = 8.5

Hope that helps!!!!!
