Absolute value of integers
: Let's mix a little algebra into our discussion of absolute value. What if we are looking for the |x|? If we know what x equals, we can do it. Follow along.
Chapter 1: Integers
Adding numbers with different signs (example)
: Use a number line to add 15 + (-46) + 29
Adding and subtracting negative numbers
: Learn how to add and subtract negative numbers. The problems solved in this video are 2 - 3 = -1 and -2 - 3 = -5 and -2 + 3 = 1 and 2 - (-3) = 5 and -2 - (-3).
Subtracting a negative = adding a positive
: Find out why subtracting a negative number is the same as adding the absolute value of that number.
Missing value addition and subtraction problems with negative numbers (examples part 1)
: Sal solves some missing value problems: -1 = 7 - __ and -10 + __ = -5 and 4 = -2 + __ and 6 + __ = -8
