Add & Subtract Integers
Apply properties of operations to add and subtract rational numbers, including real-world contexts.
M07.A-N.1.1.1Same signs: add & keep · Different signs: subtract & keep the sign of the larger absolute value · Subtracting a negative = adding a positive

M07.A-N.1.1.2Moving RIGHT = adding positive · Moving LEFT = adding negative · Subtracting a negative = moving right
Multiply & Divide Rational Numbers
Apply properties of operations to multiply and divide rational numbers, including real-world contexts.
M07.A-N.1.1.3Same signs → positive · Different signs → negative · To divide fractions: multiply by the reciprocal
Terminating & Repeating Decimals
Demonstrate that the decimal form of a rational number either terminates or eventually repeats.
M07.A-N.1.1.3Key Rule: When Does a Fraction Terminate?
| Denominator Factors | Decimal Type | Example |
|---|---|---|
| Only 2s and/or 5s | Terminating (ends) | 1/8 = 0.125 • 3/20 = 0.15 |
| Any other prime factor | Repeating (goes on forever) | 1/3 = 0.333... • 5/6 = 0.8333... |
