3 Name__ The same rules for signed numbers apply when carrying out a division. 1. A positive number divided by a positive number equals a positive number. 2. A positive number divided by a negative number (or vice versa) equals a negative number. 3. A negative number divided by a negative number equals a positive number. Here are a few examples of divisions. 62=3 (Rule 1) -62=-3 (Rule 2) 6-2=-3 (Rule 2) -6-2=3 (Rule 3) Try the following problems. Show answers as integers or decimals. 10/-2=-10/-5 = _____ Part 2 - Algebraic Equations -5/10 = 7/10= Work Check A. Determining an Unknown in an Equation when Adding or Subtracting: If you add the same term, or subtract the same term, to both sides of an equation, the equation is still valid. Let's try an example. Solve the following equation for X. X+9=12 Subtract 9 from both sides of the equation in order to obtain just X on the left side. X+9-9-12-9 X = 3 B. Determining an Unknown in an Equation when Multiplying or Dividing. If you multiply or divide both sides of an equation by the same term, the equation is still valid. Let's try an example. Solve the following equation for X. 12X=48 Divide both sides of the equation by 12 in order to obtain just X on the left side. 12X 12 48 12 X = 48 12
