WHY IS MATH WHIZ
AN IMPORTANT LEARNING TOOL?
Aft r using Math Whiz, you will b abl to:
• apply math skills to th r al world
• d v lop probl m-solving t chniqu s
• inquir , analyz , and r ason math matically
• communicat math matically
Math Whiz’s fast, continuous drill gam s and instant f dback giv
you th basic tools you n d to r ason and probl m-solv accurat ly
and ff ctiv ly.
INTRODUCTION TO MATH WHIZ
Congratulations! You hav chos n Math Whiz, th calculator and
l ctronic gam that improv s math skills. Math Whiz has thr
mod s—DRILL, CALCULATOR, and CHALLENGE.
Math Whiz DRILL is a progr ssiv s qu nc of probl ms in four skills:
addition, subtraction, multiplication, and division. Th r ar
thousands of probl ms! S lf-dir ct d and s lf-motivating, Math Whiz
Drill giv s play rs th confid nc to us math matics in v ryday
activiti s. Math Whiz us rs of all ag s and skill l v ls find that th s
f atur s h lp th m sharp n math skills at th ir own individual pac .
®Repeated Drill - Each SKILL has ight s qu ntial l v ls. At ach
l v l, th r ar t n or mor gam s—t n probl ms p r gam . At
th nd of ach gam , th play r can choos to r play that gam
to improv timing or chang to anoth r l v l or anoth r skill.
®Immediate Feedback - Diff r nt ton s and happy fac s or sad
fac s t ll th play r wh th r th answ r is corr ct or incorr ct.
®No-Fail Game Format - Incorr ct answ rs ar r cycl d into th
gam and r p at d. Gam play continu s until all probl ms ar
answ r d corr ctly.
®Self-Assessment - At th nd of ach gam , a play r’s laps d
tim is shown on th scr n. Th play r can try to improv that
tim by r p ating th gam .
As a CALCULATOR, Math Whiz p rforms arithm tic calculations for
hom or school.
Math Whiz CHALLENGE is a numb rs limination gam that k ps
play rs’ math minds working.

HOW TO USE MATH WHIZ
Math Whiz is thr fully functional l arning tools in on ! H r ’s how to us
Math Whiz. Pr ss ON to start.
For CALCULATOR
1. Pr ss CALCULATOR.
2. Input th first numb r.
3. Pr ss a function k y (+ - x ÷).
4. Input th n xt numb r.
5. Pr ss ENTER/= and th answ r will show.
6. Continu th proc ss for a multipl -st p probl m.
7. Pr ss CALCULATOR, CLR or 0 to b gin a n w probl m.
For DRILL
1. Pr ss DRILL.
2. Choos on of four skills: ADD, SUBTRACT, MULTIPLY or DIVIDE.
3. Choos a LEVEL from 1 to 8. (On is asi st.)
4. Aft r choosing SKILL and LEVEL, th scr n displays EXAMPLES.
5. Pr ss ENTER to start a gam , or CLR to choos a diff r nt SKILL or LEVEL.
• At l v ls 1 and 2, you n d to s l ct a numb r to drill.
INPUT a numb r: 0–9 in ADD and SUBTRACT, 0–12 in
MULTIPLY, 1–12 in DIVIDE.
6. Th first probl m app ars. Input an answ r, th n pr ss ENTER.
• If th answ r is corr ct, th flash s and th corr ct
answ r ton plays.
• If th answ r is incorr ct, th flash s and th incorr ct
answ r b p plays. Th gam r cycl s th probl m.
Play continues until all 10 proble s are answered
correctly.
7. At th nd of ach gam , th scr n displays a congratulatory m ssag
and th laps d tim . Your goal—b at your tim !
8. You can choos to r p at th SAME GAME or r turn to th main m nu
to choos a SKILL and LEVEL.
• Pr ss ENTER to play th sam gam , pr ss CLR to s l ct a n w
skill and l v l.
For CHALLENGE
Th obj ct of CHALLENGE is to liminat numb rs b for th numb rs
liminat you!
1. Pr ss CHALLENGE.
2. Numb rs will app ar on th scr n from l ft to right, on aft r anoth r.
You must liminat numb rs that add up to 10.
3. On th numb r pad, pr ss th numb rs adding to 10 as th y app ar on
th scr n. For xampl , if digits app ar in this ord r:
278
you should pr ss th 2 and 8 to liminat thos add nds from th
scr n. If digits app ar in this ord r:
3452
you can pr ss 3 5 2 to qual 10.
®You can pr ss up to thr numb rs to qual 10.
®If you pr ss an incorr ct numb r combination—you los !
®As soon as you l t 8 digits display across th scr n, th
CHALLENGE is ov r—you los !
4. Numb rs continu to app ar, so you must continu to liminat !
R m mb r, your goal is to stay in th gam !
®Anytim you s this pr ss ENTER to canc l it from th scr n.
This giv s you a “fr ” limination. Th n you’ll hav to start your
add nds ov r again.
5. Each tim you liminat add nds of 10, you scor 10 points. At 1,000
points CHALLENGE paus s. Th n you advanc to th n xt l v l, which
go s fa ter!
6. Th r ar 5 l v ls. At ach l v l th sp d incr as s. You’ll hav to

play for v r unl ss you l t 8 numb rs app ar on th scr n (or w ar
down th batt ri s)! S how long you can k p th CHALLENGE
going!
To cons rv batt ri s, Math Whiz is s t to turn off aft r 300 s conds, or fiv minut s, of nonus
in any mod . Pr ss th ON button to r sum play. Wh n th gam is ov r, th laps d tim at
th nd of a gam will say 300 SECS, th maximum tim . To b gin a n w gam , pr ss Math
Whiz off and on again.
