6(-3)(4)+5(4)(-5)+4(4)(-4)

6 (- 3) (4) + 5 (4) (- 5) + 4 (4) (- 4)

- 236

Solution steps

6 (- 3) (4) + 5 (4) (- 5) + 4 (4) (- 4)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

6 (- 3) (4) : - 72

6 (- 3) (4)

Apply rule

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

6 (- 3) = - 6 \cdot 3 = - 18

= - 18 (4)

- 18 (4) = - 72

- 18 (4)

Apply rule:

(a) = a

(4) = 4

= - 18 \cdot 4

Multiply the numbers:

- 18 \cdot 4 = - 72

= - 72

= - 72

= - 72 + 5 (4) (- 5) + 4 (4) (- 4)

Multiply and divide (left to right)

5 (4) (- 5) : - 100

5 (4) (- 5)

5 (4) = 20

5 (4)

Apply rule:

(a) = a

(4) = 4

= 5 \cdot 4

Multiply the numbers:

5 \cdot 4 = 20

= 20

= 20 (- 5)

Apply rule

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

20 (- 5) = - 20 \cdot 5 = - 100

= - 100

= - 72 - 100 + 4 (4) (- 4)

Multiply and divide (left to right)

4 (4) (- 4) : - 64

4 (4) (- 4)

4 (4) = 16

4 (4)

Apply rule:

(a) = a

(4) = 4

= 4 \cdot 4

Multiply the numbers:

4 \cdot 4 = 16

= 16

= 16 (- 4)

Apply rule

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

16 (- 4) = - 16 \cdot 4 = - 64

= - 64

= - 72 - 100 - 64

Add and subtract (left to right)

- 72 - 100 - 64 : - 236

- 72 - 100 - 64

- 72 - 100 = - 172

= - 172 - 64

- 172 - 64 = - 236

= - 236

= - 236

3^{2} + 6 \times 2 - 15 \div 3 + 4 \times 2

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

4 (5 + 6)

7 \times 5 + 9 - 5 \times 2

5^{3} \cdot 3
