Intro to Negative Numbers

34°C, because it is warmer. 0°C is too cold.

Draw tick marks near the middle for 0 and to the right for 34, then put a dot on each one.

Draw a horizontal line with the numbers 15 through 20 from left to right, or a vertical line with the numbers 15 through 20 from bottom to top. Draw and label tick marks for each number.

15°C is 5°C cooler, because it is farther left (or lower) on a number line.

1°C; 0°C

Greater than opens to the left (>), and less than opens to the right (<).

Both numbers are the same distance from zero, in opposite directions.

The second equation is true, because –3 is 3 units away from zero. The first equation cannot be true, because absolute values are never negative.

–12 is greater, because it is farther to the right on a number line. It is closer to zero on the negative side of the number line.

–6 < –1 < 0 < |2| < |–4|
