2-4(1/2)

Solution

2 - 4 (\frac{1}{2})

0

Solution steps

2 - 4 (\frac{1}{2})

Follow the PEMDAS order of operations

Multiply and divide (left to right)

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

4 (\frac{1}{2})

Apply rule:

(a) = a

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

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

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

4 \cdot \frac{1}{2}

Convert element to fraction:

4 = \frac{4}{1}

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

Apply the fraction rule:

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

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

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

\frac{4 \cdot 1}{1 \cdot 2}

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

\frac{4 \cdot 1}{1 \cdot 2}

Multiply the numbers:

4 \cdot 1 = 4

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

Multiply the numbers:

1 \cdot 2 = 2

= \frac{4}{2}

= \frac{4}{2}

Divide the numbers:

\frac{4}{2} = 2

= 2

= 2

= 2

= 2 - 2

Add and subtract (left to right)

2 - 2 : 0

2 - 2

2 - 2 = 0

= 0

= 0

3 \cdot (23 - 45) - 10 \cdot (38 - 39)

0 + 0 - (- 1)

20 - 8 \div 2

7 + 1 - 9 - 2 + 12

- 75 + (- 76) + (- 75) - (76)
