Q. Evaluate the expression for m=−10m = -10 and n=−2.5n = -2.5.\newlineWrite your answer as a decimal or whole number.\newlinem−n=m - n = _____
  1. Identify expression: Identify the expression to evaluate.\newlineWe need to evaluate the expression m−nm - n using the given values for mm and nn.
  2. Substitute values: Substitute the given values into the expression.\newlineSubstitute m=−10m = -10 and n=−2.5n = -2.5 into the expression m−nm - n.\newlineExpression: (−10)−(−2.5)(-10) - (-2.5)
  3. Simplify expression: Simplify the expression.\newlineSubtracting a negative is the same as adding the positive equivalent, so (−10)−(−2.5)(-10) - (-2.5) becomes (−10)+2.5(-10) + 2.5.\newlineCalculation: (−10)+2.5=−7.5(-10) + 2.5 = -7.5
