87

Solution steps

7 (3)^{2} + 9 (3) - 3

Follow the PEMDAS order of operations

Calculate exponents

(3)^{2} : 9

(3)^{2}

(3)^{2} = 9

= 9

= 7 \cdot 9 + 9 (3) - 3

Multiply and divide (left to right)

7 \cdot 9 : 63

7 \cdot 9

7 \cdot 9 = 63

= 63

= 63 + 9 (3) - 3

Multiply and divide (left to right)

9 (3) : 27

9 (3)

Apply rule:

(a) = a

(3) = 3

= 9 \cdot 3

Multiply the numbers:

9 \cdot 3 = 27

= 27

= 63 + 27 - 3

Add and subtract (left to right)

63 + 27 - 3 : 87

63 + 27 - 3

63 + 27 = 90

= 90 - 3

90 - 3 = 87

= 87

= 87

- 6 + [3 - [4 - 2 (4 - 7)]]
