Solve

3 (3 + 1) : 12

Follow the PEMDAS order of operations

Calculate within parentheses

(3 + 1) : 4

3 + 1

3 + 1 = 4

= 4

= 3 \cdot 4

Multiply and divide (left to right)

3 \cdot 4 : 12

3 \cdot 4

= \frac{1}{6}

6 \cdot \frac{1}{12} + 15 \cdot \frac{1}{4}

\frac{2021}{1 - 202 0 ^{2}}

(- 3)^{4} - 2^{4} + (- 1)^{15} + (- 4)^{3}

- 6^{2} - 9 (- 6) - 5

(- 4)^{2} - 4 (- 2) (- 2)
