Standards:

MA.4.AF.3 Understand that multiplication and division are performed before addition and subtraction in expressions without parentheses.

MA.5.C.10 Use the order of operations to solve numerical equations and expressions

MA.6.NS.11 Understand and compute whole number power of whole numbers.

MA.6.AF.4 Interpret and evaluate mathematical expressions that use grouping symbols such as parentheses.

MA.6.AF.7 Apply the correct order of operations and the properties of real numbers (e.g., identity, inverse, commutative, associative, and distributive properties) to evaluate numerical expressions. Justify each step in the process.

MA.7.NS.4 Understand and apply the concept of square root of a whole number, a perfect square and an imperfect square.

CCSS.MATH.CONTENT.5.OA.A.1

Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.

CCSS.MATH.CONTENT.5.NBT.A.2

Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.

CCSS.MATH.CONTENT.6.EE.A.1

Write and evaluate numerical expressions involving whole-number exponents.

CCSS.MATH.CONTENT.6.EE.A.2.C

Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas V = s3 and A = 6 s2 to find the volume and surface area of a cube with sides of length s = 1/2.
