OPERATIONS
I always begin with an addition problem. If you want to change the
operation sign, press any other operation key:
J
For subtraction,
K
For multiplication,
L
For division,
I
For addition.
If you want to change operations (for example from
Q
to + ), after
a set of five problems has already begun, just press the new
operation key and I will restart with a new set of five problems.
LEVELS OF DIFFICULTY
You can practice problems at five levels of difficulty:
1 2 3 4 5
1
is the easiest level,
5
the most difficult one.
You will see the number of the level in the lower left corner of the
display.
I always begin with level
1
.

Let’s practice harder problems; just press
R
until you see the
level of difficulty you want.
If you change levels (for example from
3
to
4
) after a set of five
problems has begun, just press
S
and I will restart with a new
set of five problems.
