True. When adding two numbers with the same sign, the sum will have the same sign as the two numbers being added.
True. The sum of two numbers with the same sign will also have the same sign. To understand why, you can visualize it using a number line.
If both numbers are positive, they will be to the right of zero on the number line. Adding them together will result in a number that is further to the right, still positive.
Similarly, if both numbers are negative, they will be to the left of zero on the number line. Adding them together will result in a number that is further to the left, still negative.
So, regardless of whether the numbers are positive or negative, their sum will have the same sign.
