Best Answer

When adding a positive number to a negative number, you subtract the absolute value of the smaller number from the absolute value of the larger number, then assign the sign of the larger number. In this case, the absolute value of 18 is 18 and the absolute value of -15 is 15. So, 18 minus 15 is 3. Since 18 is the larger number and it is positive, the answer is positive 3.

Well, darling, when you add 18 and negative 15 together, you get a measly 3. It's like trying to make a gourmet meal with just bread and water - not very exciting, but it gets the job done. So, in mathematical terms, 18 plus negative 15 equals 3.

Oh, dude, it's like simple math, right? So, when you add 18 and negative 15, you're basically subtracting 15 from 18. So, the answer is 3. Easy peasy lemon squeezy!
