Example Question #33 : The Number System
Add:
Simply the signs before solving. A positive sign multiplied with a negative sign will convert the sign to a negative, and a negative multiplied with a negative will convert the sign to a positive.
Example Question #2 : Negative Numbers
is equal to which of the following?
This is a straightforward problem. Remember that when adding a negative number, you are actually subtracting:
Be sure to remember that the first number is also negative, meaning we are subtracting a number from a negative number:
The answer is -6.25.
Example Question #4 : Negative Numbers
Evaluate:
The sum of two numbers of unlike sign is the difference of their absolute values, with the sign of the "dominant" number (the positive number here) affixed:
Subtract vertically by aligning the decimal points, making sure you append the 3.2 with a placeholder zero:
This is the correct choice.
Example Question #2 : Understand Distances Between Numbers On A Number Line: Ccss.Math.Content.7.Ns.A.1b
When we add a negative number, the sign turns negative. Since we are adding two negative numbers, we treat this as an addition problem and add a minus sign in the end. .
