Topic Examples CommentsEntering fractions 4/3, 1+1/3, 1 1/3 Mathematical operators on
calculator for multiplication ( ) and division ( ) differ from those on a computer keyboard (*, for multiplication and / for division)
Entering algebraic fractions
t = (v-u)/a Many students do not fully appreciate the role of parantheses, and frequently enter it as v-u/a
Entering square root symbol
3 No pre-defined key on the computer key board. Scientific calculators do provide a key.
Entering multiplication sign
a (b + c) Maple TA accepts a single space or * for multiplication
Entering exponents x^(1/4) The character ^ is unfamiliar to most of the students. Often the parantheses are left out
Entering intermediate steps
Some students prefer working the problem out, before they enter their final answer. See additional calculations in Table 3, ID 1481_q1
Entering square root symbol 3
Entering multiplication sign a (b + c)
Entering exponents

Entering fractions4/3, 1+1/3, 1 1/3
Entering algebraic fractions t = (v-u)/a t = v-u/a
