  1. The value of both of the missing numbers are -31.12.  Student work might include but is not limited to
  • -51.74 – 10.5 = -62.24
  • You have to find two values that add up -62.24
  • -31.12 + -31.12 = -62.24
  • Check: 10.5 + (-31.12) + (-31.12) = -51.74
  1. Equations might include but are not limited to,
  • 350 + 25+25+25+25-27.55-9.99
  • 350 + 25+25+25+25+ (-27.55) +(-9.99)
