Solve 6+|7-4|+2^2/2-1

$$\frac { 6 + | 7 - 4 | + 2 ^ { 2 } } { 2 - 1 }$$

Evaluate

$$13$$

Solution Steps

Subtract 4 from 7 to get 3.

$$\frac{6+|3|+2^{2}}{2-1}$$

The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of 3 is 3.

$$\frac{6+3+2^{2}}{2-1}$$

Add 6 and 3 to get 9.

$$\frac{9+2^{2}}{2-1}$$

Calculate 2 to the power of 2 and get 4.

$$\frac{9+4}{2-1}$$

Add 9 and 4 to get 13.

$$\frac{13}{2-1}$$

Subtract 1 from 2 to get 1.

$$\frac{13}{1}$$

Anything divided by one gives itself.

$$13$$

Factor
