Solve {l}{20+1}{-3*2}{+2sqrt3^2}

$$\left. \begin{array} { l } { 20 + 1 } \\ { - 3 \times 2 } \\ { + 2 \sqrt { 3 } ^ { 2 } } \end{array} \right.$$

Evaluate

$$21$$

Solution Steps

Add 20 and 1 to get 21.

$$21-3\times 2+2\left(\sqrt{3}\right)^{2}$$

Multiply 3 and 2 to get 6.

$$21-6+2\left(\sqrt{3}\right)^{2}$$

Subtract 6 from 21 to get 15.

$$15+2\left(\sqrt{3}\right)^{2}$$

The square of \sqrt{3} is 3.

$$15+2\times 3$$

Multiply 2 and 3 to get 6.

$$15+6$$

Add 15 and 6 to get 21.

$$21$$

Factor

$$3\times 7$$
