女儿老师要求家长每天按图中所示出题，媳妇将这个任务交给我，为了偷懒，用Excel VBA写了个小程序，算是开始入门Excel VBA吧！
程序如下：
Sub 生成()
Dim a, b, c, d, e As Integer
For m = 1 To 30
t = 1
While t <= 10
n = 10 * (m - 1) t
a = Int((99 - 10 1) * Rnd 10) '生成10到100之间任意数
b = Int((99 - 10 1) * Rnd 10) '生成10到100之间任意数
e = Int((99 - 10 1) * Rnd 10) '生成10到100之间任意数
c = Int((2 - 1 1) * Rnd 1) '生成1到2之间任意数
d = Int((2 - 1 1) * Rnd 1) '生成1到2之间任意数
sum_1 = a (-1) ^ c * b
sum_2 = sum_1 (-1) ^ d * e
If sum_1 > 0 And sum_1 < 100 And sum_2 > 0 And sum_2 < 100 Then
Range("A" & n) = a
If (-1) ^ c = -1 Then
Range("B" & n) = "-"
Else: Range("B" & n) = " "
End If
Range("C" & n) = b
Range("D" & n) = "="
t = t 1
End If
Wend
t = 1
While t <= 5
n = 10 * (m - 1) t * 2 - 1
a = Int((99 - 10 1) * Rnd 10) '生成10到100之间任意数
b = Int((99 - 10 1) * Rnd 10) '生成10到100之间任意数
e = Int((99 - 10 1) * Rnd 10) '生成10到100之间任意数
c = Int((2 - 1 1) * Rnd 1) '生成1到2之间任意数
d = Int((2 - 1 1) * Rnd 1) '生成1到2之间任意数
sum_1 = a (-1) ^ c * b
sum_2 = sum_1 (-1) ^ d * e
If sum_1 > 0 And sum_1 < 100 And sum_2 > 0 And sum_2 < 100 Then
Range("G" & n) = a
If (-1) ^ c = -1 Then
Range("H" & n) = "-"
Else: Range("H" & n) = " "
End If
Range("I" & n) = b
If (-1) ^ d = -1 Then
Range("J" & n) = "-"
Else: Range("J" & n) = " "
End If
Range("K" & n) = e
Range("L" & n) = "="
t = t 1
End If
Wend
Next m
Cells.HorizontalAlignment = xlCenter
Cells.VerticalAlignment = xlTop
End Sub
