Solution

\frac{1}{2} \cdot 20 - 7

3

Solution steps

\frac{1}{2} \cdot 20 - 7

Follow the PEMDAS order of operations

Multiply and divide (left to right)

\frac{1}{2} \cdot 20 : 10

\frac{1}{2} \cdot 20

Convert element to fraction:

20 = \frac{20}{1}

= \frac{1}{2} \cdot \frac{20}{1}

Apply the fraction rule:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{1 \cdot 20}{2 \cdot 1}

\frac{1 \cdot 20}{2 \cdot 1} = 10

\frac{1 \cdot 20}{2 \cdot 1}

\frac{1 \cdot 20}{2 \cdot 1} = \frac{20}{2}

\frac{1 \cdot 20}{2 \cdot 1}

Multiply the numbers:

1 \cdot 20 = 20

= \frac{20}{2 \cdot 1}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{20}{2}

= \frac{20}{2}

Divide the numbers:

\frac{20}{2} = 10

= 10

= 10

= 10 - 7

Add and subtract (left to right)

10 - 7 : 3

10 - 7

10 - 7 = 3

= 3

= 3

2 \times (1 \div 3)

(2 + 7) + 5 + 6 (3 - 4) + (- 4 [9 - 7])

(+ 3) \cdot (- 2) \cdot (- 4) \cdot (+ 5)

55 \div (4 + 1) \times 3 - 3^{2}

- 9 + 4 + (- 2)
