ADDITION
Addition is the same in algebra as in arithmetic except that we add like terms and negative numbers. Lets look at an example: U = 7 + 8 therefore U = 15
T = -5 + (-3) T = -8 Using this example can you write the rule for adding numbers with the same sign? click
What happens when we add negative numbers to positive numbers? Example T = 6 + (-4) Well T = 2 How did I get that answer? click
Try these problems G = 7 + (-6) Y = -8 + 12 R = -7 + 5 click
