The plus minus symbol means both plus and minus should be considered; or thata measurement or estimate may be plus or minus the number after the sign.For example, a measured temperature may be state as 123 +/- 0.2 C, which means temperature may be between 122.8 C and 123.2 C.An estimated attendance at an eventmay be given as 2500 +/- 100 , which means attendance should be between 2400 and 2600.The quadratic formula contains a plus minus sign, meaning that there are two roots to beobtained and given consideration.For example, t = 30 +/- 40 which means the answer may mathematically be 70 or - 10 , Realistically, the answer may be either or both numbers.
Twenty minus one.
-- If they're being multiplied or divided, then they make a minus. -- If they're being added or subtracted, then they can make either a plus or a minus. It depends on which one is bigger.
-7--1=6. A double minus makes a plus.
The compound with the formula Ag⁺ is silver ions, which have a charge of +1. Silver ions are formed when silver loses one electron.
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: 1 plus or minus i where i is the square root of negative one.
9A:2 - 1 - 1 + 1 - 1 + 3 - 2 + 6 = 7The answer is seven.
