According to the meaning of the question, you can calculate:
The same is true for calligraphy and painting:127+10-3 =134 (pieces).
134÷2=67 (width)
67- 10=57 (width)
67+3=70 (width)
So there are 57 calligraphy works and 70 paintings.
Extended data:
Several addends can be added from additive commutative law and the associative law, and the positions of addends can be exchanged at will; Or add a few addends first and then add them with other addends, and the sum remains the same.
If you subtract a number from the sum of several numbers, you can choose any addend to subtract this number and add it to the rest of the addends. For example: (35+17+29)-25 = 35-25+17+29 = 56.
