Basic Math Examples

$| 7 + - 6 |$

Step 1

Replace all occurrences of $+$ $-$ with a single $-$ . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because $1 \cdot - 1 = - 1$

$| 7 - 6 |$

Step 2

Subtract $6$ from $7$ .

$| 1 |$

Step 3

The absolute value is the distance between a number and zero. The distance between $0$ and $1$ is $1$ .
