Re: BODMAS Help me please
BODMAS
Brackets
Order
Division
Multiplication
Addition
Subtraction
so do brackets first: (3/4 + 3/8)
do divisions first
0.75 + 0.375
addition
1.125
so you now have
1.125 x 2 - 7/8
again, division first:
1.125 x 2 - 0.875
then multiplication
2.25 - 0.875
then the subtraction
1.375
(3/4 + 3/8)x2 - 7/8 = 1.375
