# Review of Algebra

## Systematic Review of Algebra

1. Add and subtract integers (signed numbers). CCSSM: 7.NS.1

2. Solve one-step equations using addition and subtraction. CCSSM: 6.EE.7 and CCSSM: 7.EE4a

3. Multiply and divide integers (signed numbers). CCSSM: 7.NS.1

4. Solve one-step equations using multiplication and division (including fractions). CCSSM: 6.EE.7 and CCSSM: 7.EE4a

• One-step equations with multiplication and division at Khan Academy

5. Distributive property, factoring out a GCF, and adding like terms.

• The distributive property appears first in 6th grade without variables (whole numbers). CCSSM: 6.NS.4 In 7th grade it is extended to rational numbers but still without variables CCSSM: 7.NS.2.
• In 8th grade the distributive property is used with variables for expanding expressions and collecting like terms. CCSSM: 8.EE.7

6. Solve multi-step equations. CCSSM: 7.EE4a

7. Factor difference of squares and trinomials (and be aware that the difference of cubes, the sum of cubes, and 4 terms can be factored).

8. Simplifying square roots and adding like terms.

9. Solve quadratic equations with no x1 term and by factoring.
