Evaluate (4+-2)/2

$\frac{4 + - 2}{2}$

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 $1 \cdot - 1 = - 1$

$\frac{4 - 2}{2}$

Step 2

Cancel the common factor of $4 - 2$ and $2$ .

Factor $2$ out of $4$ .

$\frac{2 \cdot 2 - 2}{2}$

Factor $2$ out of $- 2$ .

$\frac{2 \cdot 2 + 2 \cdot - 1}{2}$

Factor $2$ out of $2 \cdot 2 + 2 \cdot - 1$ .

$\frac{2 \cdot (2 - 1)}{2}$

Cancel the common factors.

Factor $2$ out of $2$ .

$\frac{2 \cdot (2 - 1)}{2 (1)}$

Cancel the common factor.

$\frac{2 \cdot (2 - 1)}{2 \cdot 1}$

Rewrite the expression.

$\frac{2 - 1}{1}$

Divide $2 - 1$ by $1$ .

$2 - 1$

Step 3

Subtract $1$ from $2$ .

$1$
