演算のPEMDAS順に従う

乗じて割る (左から右)

135 \div 2 : \frac{135}{2}

135 \div 2

135 \div 2 = \frac{135}{2}

= \frac{135}{2}

= - 85 + 6 + 9 - 11 + 282 - 283 - 2 + \frac{135}{2}

足して割る (左から右)

- 85 + 6 + 9 - 11 + 282 - 283 - 2 + \frac{135}{2} : - \frac{33}{2}

- 85 + 6 + 9 - 11 + 282 - 283 - 2 + \frac{135}{2}

- 85 + 6 = - 79

= - 79 + 9 - 11 + 282 - 283 - 2 + \frac{135}{2}

- 79 + 9 = - 70

= - 70 - 11 + 282 - 283 - 2 + \frac{135}{2}

- 70 - 11 = - 81

= - 81 + 282 - 283 - 2 + \frac{135}{2}

- 81 + 282 = 201

= 201 - 283 - 2 + \frac{135}{2}

201 - 283 = - 82

= - 82 - 2 + \frac{135}{2}

- 82 - 2 = - 84

= - 84 + \frac{135}{2}

- 84 + \frac{135}{2} = - \frac{33}{2}

= - \frac{33}{2}

= - \frac{33}{2}
