Please help, this is from android app "Got Math" and my phone shut down before I could get a solution.
Basically all you have to do is get to the number 427 using only the following numbers : (100,50,10,75,75,4 ) You can add/subtract/multiply/divide.
For example, if I needed you to get to the number 164, you could do : 10 + 4= 14 ; 75+75= 150; 150+14=164 !!! voila. Or a more complex problem would be get to the number 233 . To do this you would have to do ; 100/50=2 ;10-2=8; 75x4=300; 300-75=225; 225+8=233 ..... my problem is more along the lines of the latter, The answer is just eluding me.
Once you use a number you cannot use it again, it creates a new number. The game is just combining numbers to get to your target.
Please help !!
