Basic Operations with Integers and Temperature

An integer is a whole number that can be positive, negative, or zero, but does not include fractions or decimals.

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.

-5 + 3 = -2.

To multiply two integers, multiply their absolute values and determine the sign of the result: if both integers have the same sign, the result is positive; if they have different signs, the result is negative.

-4 x 6 = -24.

The absolute value of an integer is its distance from zero on the number line, regardless of direction. For example, the absolute value of -7 is 7.

To divide integers, divide their absolute values and determine the sign of the result: if both integers have the same sign, the result is positive; if they have different signs, the result is negative.

45 ÷ -5 = -9.

Temperature in Celsius is a scale used to measure temperature, where 0°C is the freezing point of water and 100°C is the boiling point.
