Operations on integers

Front

What is an integer?

Back

An integer is a whole number that can be positive, negative, or zero. Examples include -3, 0, and 5.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, |-5| = 5 and |5| = 5.

Front

How do you find the difference between two integers?

Back

To find the difference between two integers, subtract the smaller integer from the larger integer. For example, the difference between -3 and 2 is |2 - (-3)| = |2 + 3| = 5.

Front

What is the result of adding a positive integer and a negative integer?

Back

The result depends on the absolute values of the integers. If the positive integer is larger, the result is positive; if the negative integer is larger, the result is negative.

Front

What is the result of subtracting a negative integer from a positive integer?

Back

Subtracting a negative integer is the same as adding its absolute value. For example, 5 - (-3) = 5 + 3 = 8.

Front

What is the result of | -20 - 20 |?

Back

The result is 40, because -20 - 20 = -40, and the absolute value of -40 is 40.

Front

What is the absolute value of -7?

Back

The absolute value of -7 is 7, as it represents the distance from zero.

Front

What is the difference between -6 and 5 considering absolute values?

Back

The difference is 1, because the absolute value of -6 is 6 and the absolute value of 5 is 5. The difference is |6 - 5| = 1.

Front

What is |7 - 20|?

Back

The result is 13, because 7 - 20 = -13, and the absolute value of -13 is 13.

Front

What is the difference for -7 and -5?

Back

The difference is 2, because |-7 - (-5)| = |-7 + 5| = |-2| = 2.
