## Related Questions    2+-3 is the same as 2-3. So the answers is -1.      To make it simple, I'd say to simply "calculate". e.g. If you have to evaluate 33, It means 3*3*3, so it's 27. Another example, if you have to evaluate 2-5, it means 1/25, so it's 1/32.  1. Simplify 2. Factor 3.Evaluate 4. Solve Unfortunately there is no expression to evaluate!    If x=3 and y=-2, 4xy = 4(3)(-2) = 12(-2) = -24 Evaluate the expression Un = 3n - 3 for n = 1, 2, 3, 4, 5. For n = 1 you get 3*1 - 3 = 3 - 3 = 0 For n = 2 you get 3*2 - 3 = 6 - 3 = 3 and so on. Length = +sqrt[(x1 - x2)2 + (y1 - y2)2] = +sqrt[(1 - 3)2 + (-3 - 1)2] = +sqrt[4 + 16] = +sqrt(20) = +2*sqrt(5) 1. Referral: 2. Assessment: 3. Plan: 4. Implementation: 5.
