Multiplying Real Numbers HAND SIGNAL Simplify each expression. 1. 4. 7. 2. 5. 8. 3. 6. 9. Multiply Fractions: 10. 11. 12. One negative makes a negative Two negative s makes a positive Straight across (cancel or reduce either before or after)

BE CAREFUL when it comes to negatives and exponents! Scalar Multiplication of Matrices: 10. 11. BE CAREFUL when it comes to negatives and exponents! The expression -34 means the opposite of 34. The exponent 4 applies to the base 3. The negative sign is not part of the base. In the expression (-3)4, the negative sign is part of the base -3. The exponent 4 applies to the base -3. Use the order of operations to simplify each expression. 12. 14 16. 13. 15. 17.
