multiplicación inversa aditiva:
- 20 – 5 = [20 + (-5)] – [5 + (-5)]
25 = [15] – [0]
15 = 15
15 – 15 = 0
R: el inverso de "15" es "-15"
- 18 – 6 = [18 + (-6)] – [6 + (-6)]
12 = [12] – [0]
12 = 12
12 – 12 = 0
R: el inverso de "12" es "-12"
- 35 – 1 = [35 + (-1)] – [1 + (-1)]
34 = [34] – [0]
34 = 34
34 – 34 = 0
R: el inverso de "34" es "-34"
multiplicación inversa multiplicativa
- 1/4 . 4/1 = 1 . 4/4 . 1 = 4/4 =1
- 4/5 . 5/4 = 4 . 5/5 . 4 = 20/20 = 1
