Please explain, Why do we need to add when in BODMAS Rule, there is like 10 -(-7)

I will mark question with best explanations, Branliest​

Answer 1

BODMAS Rule

Let me first explain that what is BODMAS rule and some important concepts which we definitely need to solve the problem.

⠀

B refers bracket, O refers of, D refers divide, M refers multiply, A refers addition and S refers subtraction.

⠀

So by the full form only it is clear that how can we solve BODMAS problems.

⠀

First if there is any bracket in problems we need to solve the operations of that bracket. Then we need to solve "of" which stands for multiplication only. After this we need solve for multiply. After that addition and at last subtraction as S is in last.

⠀

And if you solve any question which have all these operations, then always remember the important concepts of BODMAS. The important concepts are as follows:

⠀

• (-) (-) = (+)
• (-) (+) = (-)
• (+) (+) = (+)
• (+) (-) = (-)

⠀

So now your question was that, why do we need to add when in BODMAS rule, there is like 10 - (-7).

⠀

We do it because there is two minus sign here and we discussed above that when two minus sign will be multiple, it will equal to plus.

⠀

Thus, This is why we add.

Answer 2

Required Answer :-

We know that rule of integers

If

(Negative) × (Negative) = Positive

(Positive) × (Negative) = Negative

(Negative) × (Positive) = Negative

(Positive) × (Positive) = Positive

So,

10 - (-7)

Apply rule 1

(Negative) × (Negative) = Positive

10 + 7

17

We need to add in 10 - (-7) because -ve multiplied -ve gives a positive number. And if we open bracket then we need to add the inetgers
