Fill in the missing symbol (?):
Let's solve the equation:
We'll first need to locate -3 on the number line and move four steps to the left (since minus 4 is less than zero):
This will bring us to the number -7.
Now let's move seven steps to the left (since minus 7 is less than zero):
This leaves us at the number -13..
The solution to the equation is:
Therefore, the missing sign must be:
What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
On the number line, negative numbers get smaller as you move left. Since -14 is to the right of -15, we have -14 > -15. Think of it as being closer to zero!
Add all the positive values first: 3 + 4 + 7 = 14. Then make the result negative: -14. This saves time and reduces errors!
Remember: the symbol always points to the smaller number. So -14 > -15 means -14 is greater, and the symbol points toward the smaller -15.
Absolutely! Number lines are perfect for this. Plot both numbers and see which one is farther to the right - that's the greater number.
Parentheses like (-3) help avoid confusion with subtraction. It clearly shows we mean negative three as a number, not subtracting three.
