Meaning of the notations a b/c and d/c :
1
E.g.: x = 3

a = 3, b=1 and c=2. a is the whole part of x, in other words x= 3 +
7
In fact x =

In notation form d/c, d=7 et c=2.
Your calculator allows you to carry out a range of arithmetic operations that
are expressed as or converted into fractions.
a, b and c can be replaced by a calculation in parentheses. However, in
certain cases you will be able to obtain a decimal result but not a fractional
result.
E.g.:
1 4
3 + =
 
3 [a b/c] 1 [a b/c] 2 [+] 4 [a b/c] 3 [=]
[a b/c]
[SHIFT] [d/c]
1.25 [+] 2 [a b/c] 5 [=]
[a b/c]
[SHIFT] [d/c]
You can use a fraction as an exponent:


10
x
[SHIFT] [10 ] 2[a b/c]3 [=]
Note:
• To carry out a calculation such as
-1 -1
6 [x ] + 7 [x ] [=]
[SHIFT] [d/c]
• for a fraction such as:
4
4 + 6
You can use the a b/c notation. The calculation must be entered as follows:
24 [a b/c] [(] 4 [+] 6 [)] [=]
[a b/c]
