Integers
Addition of Positive and Negative Integers 5 + 3 -5 + ( -3 ) both positive, sum positive both negative, sum negative When the signs are the same, the counters would be all the same color, so add them.
Practice this chapterAddition of Positive and Negative Integers 5 + 3 -5 + ( -3 ) both positive, sum positive both negative, sum negative When the signs are the same, the counters would be all the same color, so add them. Opposite Notation - a means the opposite of the number a
The notation - a is read the opposite of a Absolute Value Notation The absolute value of a number n is written as | n |
integers — Integers are counting numbers, their opposites, and zero ... -3, -2, -1, 0, 1, 2, 3. absolute value — The absolute value of a number is its distance from 0 on the number line. signs — the same, the counters would be all the same color, so add them. opposites — The opposite of a number is the number that is the same distance from zero on the number line, but on the opposite side of zero.
Be able to solve Application Problems Step 1. Identify what you are asked to find.
Worked example
What does “integers” mean in Integers?
- 1Use the wording this chapter gives for integers.
- 2The book says: Integers are counting numbers, their opposites, and zero ... -3, -2, -1, 0, 1, 2, 3.
- 3Do not use the meaning of absolute value. That term means The absolute value of a number is its distance from 0 on the number line.
Result: Integers are counting numbers, their opposites, and zero ... -3, -2, -1, 0, 1, 2, 3
Why. That is the meaning this chapter gives for integers.
Do not swap integers and absolute value. integers means Integers are counting numbers, their opposites, and zero ... -3, -2, -1, 0, 1, 2, 3. absolute value means The absolute value of a number is its distance from 0 on the number line.
