20 + 10 - 31 + 30 - 5 = 24
20 + 12 - 8 = 24
Answer : 130
Overland - Plus or Minus 10 miles; Plus or minus 5 minutes Oversea - Plus or Minus 20 miles; Plus or minus 5 minutes
20/10 + 10 = 12 20/(10 + 10) = 1
(-11) x (-10) + (-20) 110 + (-20) 90
20 + 10 - 31 + 30 - 5 = 24
20 + 12 - 8 = 24
In addition and subtraction, if the plus sign is larger than the minus sign, then it's a plus. For example: +10 minus -20 = -10 If the plus sign is smaller than the minus sign, the answer will be a minus. For example: -10 minus + 20 = -10 In multiplication, if you have 2 plus signs, the answer will be a plus sign. If you have 2 minus signs, the answer will be a plus sign then, too. But if you have a plus and a minus sign, then the answer will be a minus. For example: +5 x + 2 = +10 -5 x - 2 = +10 -5 x +2 = -10
20
Answer : 130
20 + 10 - 12 = 18
10 + 12/3 + 20 = 34
this is the same as 6x - 2 = 6x - 2! There are an infinite number of possibilities for "x".
Overland - Plus or Minus 10 miles; Plus or minus 5 minutes Oversea - Plus or Minus 20 miles; Plus or minus 5 minutes
-20 negative 20 minus 20
20/10 + 10 = 12 20/(10 + 10) = 1
