Question

What are some important things to think about when combining integers?

Answer 1

Step-by-step explanation:

The main important things are:-

In addition :-

+ and +, then add and put positive sign.

Eg:- 5+7=12

+ and -, then subtract and put sign of greater number.

Eg:- 2-4 = - 2

- and -, then add and put the negative sign

Eg:- - 5-7 = - 12

When multipying:-

+ and + ,multiply the numbers and put positive sign

Eg:- 5×7 = 35

- and +, multiply the numbers and put negative sign.

Eg:- - 5×7 = - 35

- and -, then multiply the numbers and put positive sign.

Note:-

Multiplication and division is done in the same way.

In subtraction, we do it the same as addition.

Eg:- Subtract - 7 from - 5

The answer is - 7 - (-5)

= - 7+5 = - 2
