Brain Workout #2

Amy figured that out to quickly, so here is another.

In each of these puzzles, you are given a number that you must construct out of several other numbers. You do this by taking the numbers and performing addition, subtraction, multiplication, and/or division operations on them. Each number must be used in the calculations exactly once, and only these four operations listed may be used. You may parenthesize your expression however you wish. For example, 5 may be obtained from 1, 2, and 3, with the expression (3 + 2) × 1.


Puzzle:

Make 19 out of 1, 4, 5 and 7

I have a 1.2-2 hr commute home, so I will check on this when I get home this evening.

[zrf2002]

((7-1) X 4)-5=19

[aggieamy07]

7-1=6
6X4=24
24-5=19

so therefore it would be ((7-1)X4)-5=19

That was easier than the first one. I was an Algebra tutor for 3 years so math is :gig: for me.

[aggieamy07]

[aggieamy07]

Closest I got was 36 and that made me royally frustrated and I gave up

[The Massacre]
