-1+2(2/3)

Solution

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

\frac{1}{3}

Solution steps

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

Follow the PEMDAS order of operations

Multiply and divide (left to right)

2 (\frac{2}{3}) : \frac{4}{3}

2 (\frac{2}{3})

Apply rule:

(a) = a

(\frac{2}{3}) = \frac{2}{3}

= 2 \cdot \frac{2}{3}

2 \cdot \frac{2}{3} = \frac{4}{3}

2 \cdot \frac{2}{3}

Convert element to fraction:

2 = \frac{2}{1}

= \frac{2}{1} \cdot \frac{2}{3}

Apply the fraction rule:

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

= \frac{2 \cdot 2}{1 \cdot 3}

Multiply the numbers:

2 \cdot 2 = 4

= \frac{4}{1 \cdot 3}

Multiply the numbers:

1 \cdot 3 = 3

= \frac{4}{3}

= \frac{4}{3}

= - 1 + \frac{4}{3}

Add and subtract (left to right)

- 1 + \frac{4}{3} : \frac{1}{3}

- 1 + \frac{4}{3}

- 1 + \frac{4}{3} = \frac{1}{3}

= \frac{1}{3}

= \frac{1}{3}

5 + 10 - 2^{3}

(96 - 14) \div 2 + 42

3^{2} (4)^{2}

7 (- 1) - 6

\frac{- 100}{- 20 + 6}
