 saraebeth's Message: Anyone have anything else? This makes sense to me, different than how I learned but I think the kids will understand this way better than the way the TE says to teach them. ADDITION: If the signs are the same then you add the two numbers and keep the sign. Ex. 6 + 2 = 8 or -6 + -2 = -8 If the signs are different, subtract the two numbers and take the sign of the larger number. Ex. -6 + 2 = -4 or 6 + -2 = 4 SUBTRACTION: Change the sign of the second number, then add the two numbers using the rules for addition, above. Ex. 6 - 2 = 6 + (-2) = 4 Ex. -6 - -2 = -6 + (+2) = -4 Ex. -6 - 2 = -6 + (-2) = -8 Ex. 6 - -2 = 6 + (+2) = 8 -Doctors Sonya and Jennifer, The Math Forum Check out our web site! http://mathforum.org/dr.math/
