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.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
