Add parenthesis to the expression below 7-3×2+6=7

Remark

Interesting question. There are two places you could put the parenthesis. We will look at both of them.

Place one

7 - (2*3) + 6 = 7 Answer

This tells you to multiply the 2 and 3 together before doing anything else. It also makes clear what to do with the 2 and 3 and what to put with whom.

7- 6 + 6 = 7. Now it's clear what to do

1 + 6 = 7

7 = 7

Place Two

7 - 3*2 + 6 = 7

(7 - 3*2) + 6 = 7

7 - 6 + 6 = 7

1 + 6 = 7

7 = 7

There are other ways to do this, but the two I've given you are fail safe.

Comment.

This is a very important lesson to be learning. People put this sort of thing on and we are not sure what to do.

x/x + 4 requires brackets everytime you list something like this. What does it mean?

Does it mean exactly what is written, so that the answer is

1 + 4 = 5?

Usually not. It usually means x / (x + 4). If I see the question written the first way, I just move onto the next question. So study what brackets do very carefully.

answer: d. $20

step-by-step explanation:

just took the test

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
