Integers + Adding & Subtracting 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.

How do you compare integers?

Back

You can compare integers using the symbols < (less than), > (greater than), and = (equal to). For example, -5 > -7.

Front

What does it mean to arrange integers from least to greatest?

Back

Arranging integers from least to greatest means putting them in order starting from the smallest number to the largest. For example, -8, -5, -3, -1.

Front

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

Back

When you add a negative integer to a positive integer, you subtract the absolute value of the negative integer from the positive integer.

Front

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

Back

Subtracting a negative integer is the same as adding its absolute value. For example, -5 - (-3) = -5 + 3 = -2.

How do you find the elevation of an object after a change?

Back

To find the new elevation, add the change in elevation to the original elevation. For example, if a submarine is at -32 feet and dives down 18 feet, the new elevation is -32 - 18 = -50 feet.

Front

What is the absolute value of an integer?

Back

The absolute value of an integer is its distance from zero on the number line, regardless of direction. For example, the absolute value of -5 is 5.

Front

How do you add two negative integers?

Back

When adding two negative integers, you add their absolute values and keep the negative sign. For example, -3 + (-2) = -5.

Front

What is the result of -35 - (-10)?

Back

The result is -25, because subtracting a negative is the same as adding a positive: -35 + 10 = -25.

Front

How do you order integers?

Back

To order integers, compare their values and arrange them from the smallest to the largest. For example, -46, -31, -9, -7, 0, 4, 15.
