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

n

is even

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

= 1

= 1 - 3 \cdot 1

Multiply and divide (left to right)

3 \cdot 1 : 3

3 \cdot 1

3 \cdot 1 = 3

= 3

= 1 - 3

Add and subtract (left to right)

1 - 3 : - 2

1 - 3

1 - 3 = - 2

= - 2

= - 2

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

(3 + 12) \div 5

\frac{( 7 \cdot 4 + 0 )}{5}

+ 19 - 15 + 4 - 12 - 4 - 5

1 0^{2} - 2 6^{2}
