**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**

End:End

"DRAW"

ClrDraw:AxesOff:FnOff
