6-5/2-2/4

Solution

6 - \frac{5}{2} - \frac{2}{4}

3

Solution steps

6 - \frac{5}{2} - \frac{2}{4}

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

Cancel the common factor:

2

\frac{1}{2}

= 6 - \frac{5}{2} - \frac{1}{2}

Follow the PEMDAS order of operations

Add and subtract (left to right)

6 - \frac{5}{2} - \frac{1}{2} : 3

6 - \frac{5}{2} - \frac{1}{2}

6 - \frac{5}{2} = \frac{7}{2}

6 - \frac{5}{2}

Convert element to fraction:

6 = \frac{6 \cdot 2}{2}

= \frac{6 \cdot 2}{2} - \frac{5}{2}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{6 \cdot 2 - 5}{2}

6 \cdot 2 - 5 = 7

6 \cdot 2 - 5

Multiply the numbers:

6 \cdot 2 = 12

= 12 - 5

Subtract the numbers:

12 - 5 = 7

= 7

= \frac{7}{2}

= \frac{7}{2} - \frac{1}{2}

\frac{7}{2} - \frac{1}{2} = 3

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

Apply rule

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{7 - 1}{2}

Subtract the numbers:

7 - 1 = 6

= \frac{6}{2}

Divide the numbers:

\frac{6}{2} = 3

= 3

= 3

= 3

\frac{3 ( - 1 ) - 3 ( 2 )}{- 5}

1 \times 2^{8}

7 \div (4 \times 2 + 9 - 10)

\frac{25 2 ^{2} - 2 3 ^{2}}{275}

(13 \cdot 14)^{3}
