Solution steps

\frac{1280}{3} - 120 + 128

Follow the PEMDAS order of operations

Add and subtract (left to right)

\frac{1280}{3} - 120 = \frac{920}{3}

\frac{1280}{3} - 120

Convert element to fraction:

120 = \frac{120 \cdot 3}{3}

= - \frac{120 \cdot 3}{3} + \frac{1280}{3}

Since the denominators are equal, combine the fractions:

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

= \frac{- 120 \cdot 3 + 1280}{3}

- 120 \cdot 3 + 1280 = 920

- 120 \cdot 3 + 1280

Multiply the numbers:

120 \cdot 3 = 360

= - 360 + 1280

Add/Subtract the numbers:

- 360 + 1280 = 920

= 920

= \frac{920}{3}

= \frac{920}{3} + 128

\frac{920}{3} + 128 = \frac{1304}{3}

\frac{920}{3} + 128

Convert element to fraction:

128 = \frac{128 \cdot 3}{3}

= \frac{128 \cdot 3}{3} + \frac{920}{3}

Since the denominators are equal, combine the fractions:

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

= \frac{128 \cdot 3 + 920}{3}

128 \cdot 3 + 920 = 1304

128 \cdot 3 + 920

Multiply the numbers:

128 \cdot 3 = 384

= 384 + 920

Add the numbers:

384 + 920 = 1304

= 1304

= \frac{1304}{3}

= \frac{1304}{3}

Convert improper fractions to mixed numbers:

\frac{1304}{3} = 434 \frac{2}{3}

\frac{1304}{3} = 434
