Magic Math Machine Touch N Tell Me Addition Subtraction Multiplication Division

Set of three Magic Math Machine and Touch N Tell Me boards for multiplication, addition, and division. Bright red and blue colors. All in great working condition. They do show some wear due to age and use, but nothing that affects function. Made in 1988 & 1993. I don’t see a date in the Touch N Tell Me board which is made by toy company Galoob.
