7

Solution steps

2 (- 4) + 5 (3)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

2 (- 4) : - 8

2 (- 4)

Apply rule

a \cdot (- b) = - a \cdot b

2 (- 4) = - 2 \cdot 4 = - 8

= - 8

= - 8 + 5 (3)

Multiply and divide (left to right)

5 (3) : 15

5 (3)

Apply rule:

(a) = a

(3) = 3

= 5 \cdot 3

Multiply the numbers:

5 \cdot 3 = 15

= 15

= - 8 + 15

Add and subtract (left to right)

- 8 + 15 : 7

- 8 + 15

- 8 + 15 = 7

= 7

= 7

5 + 7 - 2 - 4

- 7^{2} - 5 (- 7) + 3

10 \cdot 2^{4}

\frac{( 6 + 1 ) ^{2} - 14}{5}

10 \cdot 2^{2}
