Let's first solve the following equation:
We'll then locate -12 on the number line and move two steps to the left (since -2 is less than zero):
This puts us at the number -14.
Now let's move 4 steps to the right (since 4 is greater than zero):
We've reached the number minus 10.
Therefore, the solution to the equation is:
The appropriate sign will be:
What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
Addition and subtraction have the same priority in order of operations, so you must work from left to right. This ensures you get the correct answer every time, especially with negative numbers.
Negative numbers: Move left (towards smaller values)
Positive numbers: Move right (towards larger values)
Think of it as a thermometer - negative goes down, positive goes up!
On a number line, numbers get larger as you move right. So -10 is greater than -15 because -10 is further to the right. Remember: closer to zero means bigger for negative numbers!
Use the number line method! It's visual and helps you see exactly where you end up. Start at your first number and follow the moves step by step.
Yes, but make sure to use parentheses correctly: (-12) + (-2) + 4. Without parentheses, the calculator might interpret -12 + -2 + 4 differently!
