Fill in the missing sign (?):
First let's solve the equation:
We'll locate -4 on the number line and move two steps to the right (since 2 is greater than zero):
This takes us to the number -2.
Now let's move three steps to the left (since minus 3 is less than zero):
This takes us to -5.
The solution to the equation is:
Therefore, since is greater than , the missing sign must be: .
What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
You must simplify the expression before comparing! Just like in regular equations, you can't compare a complex expression to a number without knowing what that expression equals.
Start at the first number, then move right for positive numbers and move left for negative numbers. Adding (-3) means moving 3 steps to the left!
Think of the symbols as hungry mouths that always eat the bigger number! The symbol means "less than" and means "greater than".
Yes, but understanding the number line method helps you visualize negative numbers better. Use a calculator to check your work, but try the number line approach first!
