Adding Doubles just means adding the same numberr to itself. Like 2+2=4, 3+3=6, So addind doubles to 18 would be 0+0=0, 1+1=2, 2+2=4, and so forth up to 9+9=18. Maybe this will help you solve the problem.

I have a work sheet that has Add Doubles to 18 with questions asking how many blocks does this person walk each day can anyone help me please.
