I am trying to calculate heat transfer between two objects. The units are as follows:

m1: 100 g

t1: 10 degrees C

spec heat 1: 1.00 cal/g degree C

m2: 200 g

t2: 90 degrees C

spec heat 2: 0.2 cal/gm degree C

I set Q1 = Q2

m1 x spec heat 1 x delta T1 = m2 x spec heat 2 x delta T2 and solved for T final where Tfinal 1 = Tfinal 2.

My numbers aren't working out.

aaaaaaaaahhhh. got it. you have to add them and set them equal to zero.

Yes, you add them. One term is positive and the other is negative. The sum is zero.
