like this...

brackets first
(7-3)+6÷2 =
4+6÷2=

then division
4+6÷2=
4+3=

then the addition
4+3=7

BODMAS

-brackets
-orders
-division/multiplcation
-addition
-subtraction

answer is 7

Its bloody seven.

7-3= 4
6 divided by 2 = 3

4+3=7

Never heard of BODMAS before, so did it in the order presented, so 5, still at least i can spell, innit.

The answer is 7! That is a mathematical fact. How has this lasted 3 pages, and more votes for 5!!!?

Basic maths fact.

3 + 4 x 7 =

not 7 x 7

but

3 + 28, because you always multiply/divide the numbers in a sum before you add or subtract. Basic maths rule. So same rule applies for the op's question.

Tbh, I put 7 right at the start but you can obviously get both answers easily.

(7-3)=4+6 =10 /2 =5

Or
(7-3)=4, 6/2=3
4+3=7

Both work IMO.

But one way is maths, and the other way is nonsense.

Where was the multiply?

Can you not see there is two ways to write the equation?

4+6/2
4+3 (6/2)
