Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = p, where p is a positive rational number. Know and apply the properties of integer exponents to generate equivalent numerical expressions. Write an inequality for the number of sales you need to make, and describe the solutions. This week you want your pay to be at least $100.

For example: As a salesperson, you are paid $50 per week plus $3 per sale.
Graph the solution set of the inequality and interpret it in the context of the problem. Write an inequality of the form x > c or x c or x r or px + q < r, where p, q, and r are specific rational numbers. Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers. Use variables to represent numbers and write expressions when solving a real-world or mathematical problem understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set. Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true. For example, the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for. Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). 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.Īpply the properties of operations to generate equivalent expressions. 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). Include expressions that arise from formulas used in real-world problems. For example, describe the expression 2 (8 + 7) as a product of two factors view (8 + 7) as both a single entity and a sum of two terms.Įvaluate expressions at specific values of their variables. Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient) view one or more parts of an expression as a single entity. For example, express the calculation “Subtract y from 5” as 5 – y. Write expressions that record operations with numbers and with letters standing for numbers. Write, read, and evaluate expressions in which letters stand for numbers. Write and evaluate numerical expressions involving whole-number exponents.
