TI-84 Plus CE: Addition and Multiplication Math Tables

TI-84 Plus CE:  Addition and Multiplication Math Tables 


Addition Table

Multiplication Table


The programs ADDTABLE and MULTABLE create a 10 x 10 addition and multiplication table, respectively.  The programs are presented on the TI-84 Plus CE because colors are included.

I use the drawing commands on a graphing screen instead of using a matrix to accomplish the look I want.

TI-84 Plus CE Program ADDTABLE

"EWS 2019-04-14"

"BUILD THE TABLE"
{11,11}→dim([J])
For(I,2,11)
I-1→[J](1,I)
I-1→[J](I,1)
End

"ADD"
For(I,2,11):For(J,2,11)
[J](I,1)+[J](1,J)→[J](I,J)
End:End

"DRAW"
ClrDraw:AxesOff:FnOff 
For(I,1,11):For(J,1,11)

If I=1 or J=1
Then
TextColor(RED)
Else
TextColor(BLACK)
End

Text(1+14(I-1),1+20(J-1),[J](I,J))
TextColor(BLACK)
Text(1,1,"+")
End:End


TI-84 Plus CE Program MULTABLE

"EWS 2019-04-14"

"BUILD THE TABLE"
{11,11}→dim([J])
For(I,2,11)
I-1→[J](1,I)
I-1→[J](I,1)
End

"MULTIPLY"
For(I,2,11):For(J,2,11)
[J](I,1)*[J](1,J)→[J](I,J)
End:End

"DRAW"
ClrDraw:AxesOff:FnOff 
For(I,1,11):For(J,1,11)

If I=1 or J=1
Then
TextColor(GREEN)
Else
TextColor(BLACK)
End

Text(1+14(I-1),1+20(J-1),[J](I,J))
TextColor(BLACK)
Text(1,1,"*")
End:End
