19

Solution steps

8 + 10 + 2 \div 4 \times 2

Follow the PEMDAS order of operations

Multiply and divide (left to right)

2 \div 4 \times 2 : 1

2 \div 4 \times 2

2 \div 4 = \frac{2}{4}

= \frac{2}{4} \times 2

\frac{2}{4} \times 2 = 1

\frac{2}{4} \cdot 2

Cancel the numbers:

\frac{2}{4} = \frac{1}{2}

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

Convert element to fraction:

2 = \frac{2}{1}

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

Cross-cancel common factor:

2

= 1

= 1

= 8 + 10 + 1

Add and subtract (left to right)

8 + 10 + 1 : 19

8 + 10 + 1

8 + 10 = 18

= 18 + 1

18 + 1 = 19

= 19

= 19

\frac{1}{4} (- 1 - \frac{5}{2} + 9)

(9 + 2) \times 6 - 5

2 \times (- 1 \div 2)

2 (8 - (- 1)) - 3 (6 + 4)

17 - 7 \cdot (- 4)
