I use a different method. I told my daughter to name it so that she would think of it as her own. She called it the "ten and minus method" Here it is: 34-18 1. so get the 18 to the nearest multiple of ten which her is 20. So we added 2 2. From 20 to 30 is 10 and to 34 it is 10+4 which is 14 3. 14+2 = 16
