CSET Multiple Subjects Subtest 2: Math and Science Practice Test

The main idea is how we organize calculations so everyone gets the same result. We evaluate in stages: first anything inside parentheses, then any exponents, then the next level which handles multiplication and division together (from left to right), and finally the last level for addition and subtraction (also from left to right). The sequence shown follows that structure: it places parentheses first, then exponents, then the multiplication/division stage, and finally the addition/subtraction stage. The key rule to remember is that within the same stage you work from left to right, so multiplication and division are not fixed in order—you follow the order they appear from left to right; the same goes for addition and subtraction. For example, in an expression with both multiplication and division, you do whichever comes first as you read left to right, then proceed. This aligns with the standard rule many teachers use, often remembered as PEMDAS/BODMAS, with the emphasis on left-to-right within the same level.
