MA.8.NSO.1.7 · Number Sense and Operations and Probability
Multi-step order of operations in 8th grade adds exponents and roots to the mix, as in (−1/2)^2 + √(2^3 + 8). Expressions run up to six steps and use rational numbers throughout, including negative and fractional bases.
The FAST uses equation editor items for the exact value and multiple choice items that turn on a single misplaced step. Radicands stay inside perfect squares up to 225 and perfect cubes from −125 to 125, so every root comes out to an integer.
These come straight from Algebro's 8th grade pre-algebra question bank, easiest first. Answer one, check it, then move to the next.
