(-12)^2-4\times 1\times 15

(- 12)^{2} - 4 \cdot 1 \cdot 15

84

Solution steps

(- 12)^{2} - 4 \cdot 1 \cdot 15

Follow the PEMDAS order of operations

Calculate exponents

(- 12)^{2} : 144

(- 12)^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

n

is even

(- 12)^{2} = 1 2^{2} = 144

= 144

= 144 - 4 \cdot 1 \cdot 15

Multiply and divide (left to right)

4 \cdot 1 \cdot 15 : 60

4 \cdot 1 \cdot 15

4 \cdot 1 = 4

= 4 \cdot 15

4 \cdot 15 = 60

= 60

= 144 - 60

Add and subtract (left to right)

144 - 60 : 84

144 - 60

144 - 60 = 84

= 84

= 84

1 1^{2} - 2 \times 5

37 - 5 \div 2 + 4 \times 3

\frac{5}{9} (62 - 32)

5 (2) - 14

(15 - 9) \times 8 - 23
