如何让模型学会100以内的加减法？

I have done a lot of rounds with the 104M model, and the data format is as follows: {"conversations": [{"role": "user", "content": "81 + 14="}, {"role": "assistant", "content": "95"}] {"conversations": [{"role": "user", "content": "94 + 35="}, {"role": "assistant", "content": "129"}] {"conversations": [{"role": "user", "content": "28 + 17="}, {"role": "assistant", "content": "45"}] {"conversations": [{"role": "user", "content": "86 + 94="}, {"role": "assistant", "content": "180"}] {"conversations": [{"role": "user", "content": "75 + 54="}, {"role": "assistant", "content": "129"}] {"conversations": [{"role": "user", "content": "3 + 11="}, {"role": "assistant", "content": "14"}] {"conversations": [{"role": "user", "content": "29 + 64="}, {"role": "assistant", "content": "93"}] {"conversations": [{"role": "user", "content": "71 - 25="}, {"role": "assistant", "content": "46"}] {"conversations": [{"role": "user", "content": "28 - 57="}, {"role": "assistant", "content": "-29"}] {"conversations": [{"role": "user", "content": "0 + 97="}, {"role": "assistant", "content": "97"}] {"conversations": [{"role": "user", "content": "89 - 54="}, {"role": "assistant", "content": "35"}] {"conversations": [{"role": "user", "content": "35 + 19="}, {"role": "assistant", "content": "54"}] {"conversations": [{"role": "user", "content": "97 + 43="}, {"role": "assistant", "content": "140"}] {"conversations": [{"role": "user", "content": "11 + 48="}, {"role": "assistant", "content": "59"}] {"conversations": [{"role": "user", "content": "45 - 44="}, {"role": "assistant", "content": "1"}] {"conversations": [{"role": "user", "content": "5 - 93="}, {"role": "assistant", "content": "-88"}] {"conversations": [{"role": "user", "content": "68 - 15="}, {"role": "assistant", "content": "53"}] {"conversations": [{"role": "user", "content": "10 - 70="}, {"role": "assistant", "content": "-60"}] {"conversations": [{"role": "user", "content": "80 - 79="}, {"role": "assistant", "content": "1"}] {"conversations": [{"role": "user", "content": "73 + 24="}, {"role": "assistant", "content": "97"}] ......
