Solve the following equation:
Let's begin by locating negative 30 on the number line and moving 4 steps to the right (since 4 is greater than zero):
We reach negative 26.
Resulting in the following exercise:
Now let's locate negative 26 on the number line and move 8 steps to the left (since negative 8 is less than zero):
We reach negative 34
What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
Because you have mixed signs! You must follow the rules: negative + positive means subtract, and negative + negative means add and keep negative. Don't ignore the individual signs of each number.
Positive numbers: move right. Negative numbers: move left. So +4 means 4 steps right, and +(-8) means 8 steps left from your current position.
Yes! You can group negatives together: . Addition is commutative, so order doesn't matter for the final answer.
Use the number line method! Start at the first number and physically move step by step. Positive = right, negative = left. This visual approach prevents sign errors.
Yes! Check it: , then . You can also think: I owe 4, so I owe 8 more = owe $34 total.
