1 SOME OF EVERYTHING FINAL REVIEW
2 Hilltop High School Math 9 Review Complete this review package to help ensure you are ready for Math 10C! Operations with positive and negative numbers Multiplying and Dividing positive and negative numbers: If the signs are the same (both positive or both negative) the answer will be positive. If the signs are different (one positive and one negative), the answer will be negative Adding and Subtracting positive and negative numbers: Adding a positive number Subtracting a negative number Subtracting a positive number Adding a negative number Addition (move to the right on a number line) Subtraction (move to the left on a number line)
3 More Practice the more you practice mental math, the better you will get and the faster you will get without having to resort to using your calculator. Roll several dice and add, subtract, or multiply the values without using a calculator. Using a deck of cards, flip up two or more cards and add or multiply the values together. For an etra challenge, let the black cards be positive numbers and the red cards be negative. You can also flip them into fractions to add, subtract, multiply or divide.
4 Pythagorean Theorem Helpful Reference: Tips: Identify and label each side Fill in the blanks in your formula Solve for the unknown Remember to take the square root to find the final answer! Solve for the unknown side in each of these triangles. Round to the nearest tenth if necessary
