Question about Texas Instruments TI-15 Explorer Calculator
My ti-15 has the n/d designation on it and it will not go away.
Read the manual to find out it means.The results that are rational numbers can be displayed as decimal numbers, mixed numbers (a b/c) or improper fractions (d/c). Irrational numbers such as Pi, SQRT(2), SQRT(3), etc approximated by their decimal representation.
Look at the keyboard.Tthere must be a key that allows you to convert from fractions to decimals (always) and from decimals to fractions (sometimes). The key may be marked F--D, S--D, Change. You may also have to press the [a b/c] key to change representations.
