11 9

99.

Step-by-step explanation:

-First, we multiply -9 times 11, -9 x -11 = 99 the (-) is not putted. The (-) shouldn´t be put in the answer.

-Why? Because when you multiply two negative numbers together, the first one flips the sign from positive to negative, and the second one flips it back. In other words, negative numbers cancel each other out: when you multiply a negative number by a negative number, you get a positive number.

-You can find the answer in a lot of ways. As we know that the answer doesn´t have a negative sign, we only have to concentrate on how to find the answer.

A). Multiplying ( 11 x 9 = 99 ).

B). Adding and Multiplying ( 11 + 11 + 11 + 11 + 11 + 11 + 11 + 11 +11 = 99 )

-How to know if the answer is correct?

A). Dividing ( 99 ÷ 11 = 9 )

B). If you know that the quotient should be 99, but multiplying the numbers that are given give you the wrong answer. Then, you have to look for the numbers that multiplied give you the correct answer.

-Hope this helps.
