Adding and Subtracting Integers word problems

An integer is a whole number that can be positive, negative, or zero, but not a fraction or decimal.

To add two integers with different signs, subtract the smaller absolute value from the larger absolute value and keep the sign of the integer with the larger absolute value.

The result can be positive, negative, or zero, depending on the absolute values of the integers.

Subtracting an integer is the same as adding its opposite. For example, subtracting -3 is the same as adding +3.

Depth refers to how far below a reference point (like sea level) something is, while elevation refers to how high above a reference point something is.

Subtract the depth of Marie from the depth of Nancy: -15 - (-22) = 7 feet.

Change in elevation = Final elevation - Initial elevation.

Change in temperature = Final temperature - Initial temperature = -27 - (-15) = -12°C.

It means the temperature is getting lower, which can be represented by a negative change in temperature.

A gain is represented by a positive integer and a loss is represented by a negative integer. For example, gaining 9 yards is +9 and losing 22 yards is -22.
