Question

Simplify :
4+(-5)+8-(-10)+9

Answer 1

I think it would be the correct answer

Answer 2

Answer:

26

Step-by-step explanation:

First you have to know about the signs.

+ = positive (addition)

- = negative (subtraction)

(+) × (-) = -

(-) × (+) = -

(+) × (+) = +

(-) × (-) = +

So here in the question

4+(-5)+8-(-10)+9

First lets take 4+(-5)

So here it is +(-) that is (+) × (-) = -

So you have to subtract here.

4 - 5 = -1 (Subtracting small number from big number)

then we get the question as -1+8-(-10)+9

so when we simplify -1+8 we use (-) × (+) = -

So we have to subtract again.

8-1 = 7

so we get the question simplified as 7-(-10)+9

When we take 7-(-10)

We use (-) × (-) = +

So we add here.

7+10 = 17.

We get the question to the last step as 17+9.

We again add here.

17+9 is 26.

So we have got the answer as 26.
