Algebra 2: Real Numbers and Algebraic Expressions Name: ___________________________________________ Topic A4: Exponents and Scientific Notation | VERSION B 1. The following is a list of steps for the order of operations. Write the correct step number in the blanks. Write the following with positive exponents. Then simplify as much as possible. 7. 3!! = 8. ______ Simplify all numbers with exponents, working from left to right if more than one of these expressions is present. ______ Perform all additions and subtractions left to right. ______ Work all multiplications and divisions left to right. 3 2 !! = ______ Begin with the expressions in the innermost parentheses or brackets and work your way out.
