in algebra if you have a problem like
-2+2 will the answer be negative or positive? can you please explain why
If you have 2 dollars and give away 2 dollars, you have 0.
However, if you have 2 dollars and owe your mom 3 dollars, you have - 1.
i don't understand
You have 2 dollars >> + 2
You give away your 2 dollars >> - 2
You have no money left >> 0
However, if you have 2 dollars and owe your mom 3 dollars, you'll still owe her 1 dollar >> 2 - 3 = -1
Your answer will be zero. When you have a negative number like that in the beginning, you can make the problem much simpler by changing it. To change the problem, circle each number with the sign directly in front of it. So in this problem, circle the "-2" and the "+2". Now, rearrange these two numbers with their signs so you have "+2" "-2" Take away the circles, and your new problem is +2-2. Since positive 2 is just 2 your problem ends up as 2-2 which = 0
thank you
You're welcome.
In algebra, when you want to add two numbers, you need to consider their signs. In this case, we have -2 + 2.
The first number, -2, is negative, while the second number, +2, is positive. When you add a negative number and a positive number, you can think of it as subtracting the absolute value of the negative number from the positive number.
In this example, we have +2 - 2. Subtracting 2 from 2 gives us zero.
So, the answer to -2 + 2 is 0, which means the result is neither positive nor negative. This is consistent with the idea that adding equal positive and negative numbers cancels them out and leaves us with zero.
