- Worksheet 1
For those of you who have not watched the videoclips on "Real Numbers in Operation",
please watch them to understand the concepts behind the Addition and Subtraction of Integers.
Then you link it back to the technique we discuss in class:
(1) By looking at the numerical value, identify the larger one.
(2) Adopt the sign of this number (+ or -)
(3) If both numbers have the same sign, we'll add the numerical values. If both numbers have different signs, then we'll subtract the numerical values.
