Study Notes
Signed Number Calculations
- Calculate expressions using the best method for addition and subtraction of signed numbers.
- Follow the rules for adding and subtracting positive and negative numbers
- Combine like terms (positive with positive, negative with negative)
Ordering Numbers
- Calculate the values of E, F, and G.
- E = (-5.2) + (-7.1) = -12.3
- F = (-4.1) - (-6.5) + (-5.2) = 2.4 - 5.2 = -2.8
- G = (11.1) - (19.2) = -8.1
- Arrange the values E, F, and G in decreasing order: 11.1, -4.1, -5.2
- Important: Follow the proper order of operations to calculate the values.
