What would you like to do?
9 + 3 = 12
i think the equation would be : 4+ ( - 3 ) = so that would probably be back to four if it was four plus minus three you would add three then minus it which would make it F…OUR.. ( but im not completely sure so don't just depend on this )
-2 Same as plus 3 minus 5. If you don't believe it, Put +10 in front and take it away afterwards : 10-5+3-10 is 8-10 is -2. If you keep the sign in front of each number, then …you can switch around: (-5)+(+3) is (+3)+(-5) is (-2)
10x3+8=80-60+? 30+8=20+? 38=20+? 38-20=? 18=? The answer is 18.
it equals -15
