Take Note: Recall that when we "do" math operations, we follow the order of operations, PEMDAS. Since solving equations is essentially "un-doing" operations, we reverse the order of operations. Order the following operations in the reverse order of PEMDAS.
  1. parentheses & other grouping symbols
  2. subtraction/addition
  3. division/multiplication
  4. exponents

Take Note: Summarize the process of solving a two-step equation.
Take Note: Just as PEMDAS is a helpful mnemonic device for remembering the order of operations, SADMEP can help you remember the order in which to "un-do" operations when solving equations.
