• Make the number 63 with the following operators: +, -, x en / and figures: 1, 6, 9.
  • (1+6)*9=63
    (6+1)*9=63
    9*(1+6)=63
    9*(6+1)=63
• Make the number 44 with the following operators: +, -, x en / and figures: 3, 9, 10, 13. 
  • (3*(9+10))-13=44
    (3*(10+9))-13=44
    ((9+10)*3)-13=44
    ((10+9)*3)-13=44
