Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum.

On the third week, they doubled the sale of their second week.

Although, the number 5 is mentioned first in the sentence that does not mean that it would come first in the equation. In these lessons, we will cover some examples of integer word problems with two unknowns.

Answer: -2.) When multiplying integers, we can think of multiplying "blocks" of negative numbers.

(a) Here is an integer times an integer: Notice that we were multiplying a positive number by a negative number and our result was negative.

Similarly, we can show: (b) ` -6 xx 2 = -12` (negative times positive gives negative) and (c) `-3 xx -7 = 21` (multiplying 2 negatives gives a positive) The acceleration due to gravity (1 g) on the earth is about −10 ms. This is a convention.) On the planet Jupiter, the acceleration due to gravity is 2.65 times the acceleration due to gravity on the Earth.
