# What does a minus plus a minus equal?

A minus and a minus (-4+-5) is a minus. It only becomes a plus if two minus's are timesed together. eg. -4 + -5 = -9 -4 x -5 = 20 It is easier to work with if you have no …negatives on the second number. You can switch the two symbols that are next to each other without disturbing the equation. For example: -4 + -5= -4 - 5= -9 It makes it easier to trace on a number line. I hope this helps more than confuses

# What is a minus minus a plus equals?

The question isn't too clear, but I'll assume it means, "what is a negative number minus a positive number?" The answer to that is: a negative number. To explain why, imagin…e the number line. A negative number is to the left of 0. Subtraction says to go reverse the direction you would if you were adding the number. Adding a positive number would mean you're going to the right. So you just go farther to the left. Wherever you are, you're still on the left side of the 0, so the result is a negative number.

# A plus b equals 8 and a minus b equals 9?

Solve one of the formulas for A, then substitute that into the other formula to solve for B, then substitute the solution for B into one of the formulas to solve for A. Here… is how: Givens: A+B=8 A-B=9 So: If A+B=8 then A=8-B Next, substitute this into the other formula... A-B=9 (8-B)-B=9 (-B) - B = 1 (-2B) = 1 B= (- 1/2) Next, substitute the solution for B into one of the formulas to solve for A.... A+B=8 A+ (-1/2) = 8 A = 8 and 1/2 So... B= (- 1/2) A = 8 and 1/2

# Why does minus and minus equal plus?

Because a minus changes the sign. If you take a plus and change it to a minus, you get a minus. If you take a minus and change it to a minus, it changes back into a plus. …Because you have only two options, minus and plus, here are all the options: + & - = -+ & + = +- & + = -- & - = + ===== Everything above the double line is a misleading, even dangerous discussion. When it's all over, both the questioner and the responder think they have it all worked out, where in reality, it's all meaningless. The main problem is: Neither of them ever explains what ' and ' means in the question, or what ' & ' means in the answer. Neither of those is a mathematical operation. The statement in the question, and the list of 4 'rules' in the answer, are correct for some mathematical operations and either indeterminate or dead wrong for others. The question says: " ... minus and minus equal plus. " -- If ' and ' means multiplication or division, then it's a true statement. -- If ' and ' means subtraction, then it may or may not be true, depending on the size of the two numbers. -- If ' and ' means addition, then it's always false. In the list of 4 items in the answer: -- If ' & ' means multiplication or division, then all 4 items are correct (but almost impossible to remember in this form). -- If ' & ' means addition, then items #1 and #3 are sometimes true and sometimes false, item #2 is always true, and item #4 is always false. -- If ' & ' means subtraction, then item #1 is always false, items #2 and #4 are sometimes true and sometimes false, and item #3 is always true.
