7 + 1 = 8 8 - 7 = 12 + 6 = 8 8 - 2 = 6
6 + 2 = 8 8 - 6 = 23 + 5 = 8 8 - 3 = 5
5 + 3 = 8 8 - 5 = 34 + 4 = 8 8 - 4 = 4记住这4个算式我就会说出其他几个算式？7677657655765567655677655678188118811 + 8 = 9 9 - 1 = 8
8 + 1 = 9 9 - 8 = 12 + 7= 9 9 - 2 = 7
7 + 2= 9 9 - 7 = 23 + 6 = 9 9 – 3 = 6
6 + 3 = 9 9 – 6 = 34 + 5 = 9 9 – 4 = 5
