Students solve multi-step order of operations problems with rational numbers, including grouping symbols, whole-number exponents, and absolute value. Expressions stay at six steps or fewer, but they mix signed fractions and decimals, so the order the steps happen in decides the answer.
How the FAST tests this benchmark
The FAST tests this with equation editor items where students enter the exact value of an expression. The errors that cost points are working left to right instead of by the order of operations, dropping a negative inside absolute value bars, and squaring a negative base that was never wrapped in parentheses.
