This is supposed to be a 6th grade problem. using integers 8 4 2 1 in order, create an equation to equal 18 and another to equal 19. you may use + - % X and exponents (^) in the same order. Now if the integers and operands (including exponent) are to be in any order then the answers are simple. 8 + (4+1)*2 = 18 8*2 + 4 - 1 = 19 But, if not only the integers 8,4,2,1 are to be in order, but also the operands, then it seems impossible. I think the integers must be in order at least. Can anyone see if it's possible or not to answer this question with integers in order but the operands in any order? Integers are to be used once only. Operands can be used multiple times.
