When you add integers with different signs, you must subtract and take the sign of the largest number.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When adding integers with different signs, the rule is to subtract the smaller number from the larger number and take the sign of the larger number. This is because when we add a positive number and a negative number, the result will always have the sign of the larger number. For example, if we add +5 and -3, we subtract 3 from 5 and take the sign of 5, which is positive. Therefore, the statement is true.Rate this question:

-8 x 5 =
- A.
40
- B.
-40
- C.
-3
Correct Answer
B. -40Explanation
When you multiply a negative number by a positive number, you're essentially combining groups of the positive number but in the opposite direction.
So, when you have -8 multiplied by 5, it means you have 5 groups of -8.
Here's how you can visualize it:
-8 + (-8) + (-8) + (-8) + (-8) = -40
Each group of -8 adds up to -40. So, when you combine 5 groups of -8, you end up with a total of -40.
That's why -8 multiplied by 5 equals -40.Rate this question:
