Integers are whole numbers that describe opposite ideas in mathematics. Integers can either be negative(-), positive(+) or zero. The integer zero is neutral. It is neither positive nor negative, but is an integer. Integers can be represented on a number line, which can help us understand the valve of the integer. Watch Integers Videos to learn more.
Are to the right of zero. Are valued greater than zero. Express ideas of up, a gain or a profit. The sign for a positive integer is (+), however the sign is not always needed. Meaning +3 is the same value as 3.
Are to the left of zero . Are valued less than zero. Express ideas of down or a lose. The sign for a negative integer is (-). This sign is always needed.
Opposite integers always have a “net worth” of 0. This is called the ZERO PRINCIPAL. Opposite integer have the same “absolute value”, meaning the distance from the points on a number line to zero is the same.This can be referred to as the integers magnitude.
Movement on a Number Line Magnitude and Direction
Every integer represents a magnitude and a direction. The integer +3 describes a movement of 3 units in a positive direction.(right) . The sign (+) tells you the direction. The number (3) indicates how far to move or the MAGNIUDE( a move ment of 3 units).
