Common Core Standards Understanding Operations - Multiply/Divide
Grade:	7th Grade
Standard:	Math.7.NS.2a or 7.NS.A.2.A
Description:	Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (–1)(–1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts.
Standard:	Math.7.NS.2b or 7.NS.A.2.B
Description:	Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then –(p/q) = (–p)/q = p/(–q). Interpret quotients of rational numbers by describing real-world contexts.
Standard:	Math.7.NS.2c or 7.NS.A.2.C
Description:	Apply properties of operations as strategies to multiply and divide rational numbers.
Standard:	Math.7.NS.2d or 7.NS.A.2.D
Description:	Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.

MULTIPLY INTEGERS

The product of two positive numbers is positive.
The product of two negative numbers is positive.
The product of one negative number and one positive number is negative.

EXAMPLES

9 × 11 = 99	-9 × (-11) = 99
-9 × 11 = -99	9 × (-11) = -99

DIVIDE INTEGERS

The quotient of two positive numbers is positive.
The quotient of two negative numbers is positive.
The quotient of one negative number and one positive number is negative.

EXAMPLES

99 ÷ (-9) = -11	99 ÷ (-11) = -9
-99 ÷ (-9) = 11	-99 ÷ (-11) = 9
