Divide before adding, you don't need the second brackets.

i said 5 as the sum would be 4+6/2= 5

if it were as Helen said (7-3)+(6÷2)= 7 or 7-3+(6÷2)=7

ooo well i got it wrong.. back of the class for me then

Why 7? you do whatever is in the brackets first, so 5

almost, it should be done in this order;

BODMAS

Brackets
Orders - dont ask...
Division
Multiplication
Addition
Subtraction

so (7-3)+6÷2 is equivalent to (7-3)+(6÷2)

Do the brackets first. so 4 + 6 /2 =?

Then orders (powers) - There are none

Then multiplications or divisions so 4 + 3 = ?

Finally additions and subtractions so 4 + 3 = 7

I can to a cash, tax and vat calc and still can't get simple maths right

Bri w · 12-10-11, 09:08 PM

oh eck! I got it as 3.

I saw the equation as nothing in front of the bracket = 0.(7-3)+6/2=3

Doh!

sorry wth how is the answer ever going to be 7?

do the sum in the brackets first. then do the remaining sum. the sum in the brackets has to be done first. its a bit like foreplay. ignore it and you'll get the wrong end result.
