Core Connections: True or False Questions

A statement is true if it is always true. If any part of a statement is false or if you can think of even one example that makes the statement false, the entire statement is false.

Write True or False. If your answer is False, explain your thinking.

  1. The absolute value of any negative number is greater than zero.
  1. The smallest positive number is greater than the absolute value of any negative number.
  1. On a number line, numbers with the same absolute value are the same distance from zero.
  1. The absolute value of zero must be greater than the absolute value of any negative number.

Shortened Rules for Multiplying and Dividing Integers

NOTES

If the signs are the SAME, then the answer is POSITIVE. Same Sign = Positive

If the signs are DIFFERENT, then the answer is NEGATIVE. Different Signs = Negative

Multiplying and Dividing Signed Numbers

Multiplication is fast addition. In other words, you can multiply when you have to add the same number many times.

You can multiply more than two numbers. Multiply the numbers, then decide whether the answer is positive or negative.

  • If there is an even number of negative numbers, the answer will be positive.
  • If the number of negatives is odd, the answer will be negative.

This would be a frustrating problem to do without a calculator.

But if you write it as a fraction, you can simplify to find an easier problem to solve.

Workbook page 31

Divide the numerator and denominator by the same number.

 

 

 

You only need to simplify enough for YOU to solve the problem.
