Evaluate.

(14) - 2 - (50⋅2) ⋅1-1

From the order of operations, we do parens, then multiply/divide, then add/subtract, rewriting each step to keep everything clear:

(14) - 2 - (50 ⋅ 2) ⋅ 1 - 1

14 - 2 - 100 ⋅ 1 - 1 [parens are finished]

14 - 2 - 100 - 1 [multiplication is finished]

- - we do the subtraction left to right, but here are the steps:

12 - 100 - 1

-88 - 1
