1\times 1+2\times (-1/2)+3\times 0

1 \cdot 1 + 2 \cdot (- \frac{1}{2}) + 3 \cdot 0

0

Solution steps

1 \cdot 1 + 2 (- \frac{1}{2}) + 3 \cdot 0

Follow the PEMDAS order of operations

Multiply and divide (left to right)

1 \cdot 1 : 1

1 \cdot 1

1 \cdot 1 = 1

= 1

= 1 + 2 (- \frac{1}{2}) + 3 \cdot 0

Multiply and divide (left to right)

2 (- \frac{1}{2}) : - 1

2 (- \frac{1}{2})

Apply rule

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

2 (- \frac{1}{2}) = - 2 \cdot \frac{1}{2}

Convert element to fraction:

2 = \frac{2}{1}

= - \frac{2}{1} \cdot \frac{1}{2}

Cross-cancel common factor:

2

= - 1

= 1 - 1 + 3 \cdot 0

Multiply and divide (left to right)

3 \cdot 0 : 0

3 \cdot 0

3 \cdot 0 = 0

= 0

= 1 - 1 + 0

Add and subtract (left to right)

1 - 1 + 0 : 0

1 - 1 + 0

1 - 1 = 0

= 0 + 0

0 + 0 = 0

= 0

= 0

25 + 100 + (- 19) + (- 11) + 18

- 2^{2} + 8 (- 2) + 12

1/2 + (2) - 1/5

\frac{5}{10} \times 1

3 (2) + 6
