absolute value, Integers and Comparing Integers

Front

What is absolute value?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. It is always a non-negative number.

Front

How do you find the absolute value of a negative integer?

Back

The absolute value of a negative integer is the positive version of that integer. For example, |-5| = 5.

Front

What is the absolute value of 0?

Back

The absolute value of 0 is 0, since it is at the origin on the number line.

Front

How do you compare two integers?

Back

To compare two integers, determine their positions on the number line. The integer further to the right is greater.

Front

What is the distance between -3 and 4 on the number line?

Back

The distance is |4 - (-3)| = |4 + 3| = |7| = 7.

Front

If a bird is at an elevation of 150 feet and a fish is at a depth of 20 feet, what is the distance between them?

Back

The distance is |150 - (-20)| = |150 + 20| = |170| = 170 feet.

Front

What does the symbol '>' mean when comparing integers?

Back

The symbol '>' means 'greater than'. For example, 5 > 3 means 5 is greater than 3.

Front

What does the symbol '<' mean when comparing integers?

Back

The symbol '<' means 'less than'. For example, -2 < 1 means -2 is less than 1.

Front

What is the result of |-22|?

Back

The result is 22, as absolute value removes the negative sign.
