+129852 10, 50, 5, 25 and 500 to make 575
One way :
500 - 25 + (10/5) * 50 =
475 + 2 * (50) =
475 + 100 =
575
+26393 PUZZLE 1 10,50,5,25,and 500.
Use these numbers to make the number 575.
\(\begin{array}{rcll} 575 &=& 500-50-(10-5)\times 25 \\\\ 575 &=& 500-25+50+5\times 10 \\\\ 575 &=& 500-(10-50+25)\times 5 \\\\ 575 &=& 500-25+\frac{10\times 50}{5} \\\\ 575 &=& \frac{5\times 25\times 50-500}{10} \\ \end{array}\)
\(\begin{array}{rcll} 575 &=& (5\times 10)+25+500 \\\\ 575 &=& (5\times 25)-50+500 \\\\ 575 &=& 25+(50+5)\times 10 \\\\ 575 &=& (25-10)\times 5+500 \\ \end{array} \)
\(\begin{array}{rcll} 575 &=& 25+50+500 \\ \end{array}\)
+319 You all did very well... But...Gh0sty15 You must you all numbers... I am sorry but you were not able to compete in this challenge... CPhill and heureka you all have very good answer Good job
+2446 I don't understand why Gh0sty was unable to complete the challenge. What you said is contradictory to your original post.
I have highlighted, in red, where Gh0sty thought it was unnecessary to use every number:
