Is there an untimed mode? Can it be used as a calculator? How does it compare to Math Whiz?

I ordered have ordered many of these for classroom teachers as gift. The last purchase was in 2011. At that time, none of them had an "untimed mode". It is designed to see how quickly they can do math facts in a minute. Not a calculator. I do not know Math Whiz.

Yes, there is an untimed mode. Instructions for setting this can be found in the product user guide here: www.learningresources.com/text/pdf/6965_webguide.pdf

It cannot be used as a calculator and there is a mode without the timer. I have never used Math Whiz so I can't answer that question.

Sort of...it has an interval timer function, but you can only program 5 intervals, which with recovery isn't enough intervals for me. I have not played with this function more than once or twice so there may be a work around, but it in my opinion this is one of the negatives of the watch. Otherwise I like the watch very much. You ma look at the run trainer 2.0 for improvements of this feature.

It keeps and displays the last time you set until you set a new time. You can keep using it to measure the same time without entering the time again. So, yes.

I believe you can do that, but I only used for single count-up timer. Sorry for not being able to give you a definite answer.

I have three of these devices - two brands - neither count up = they only accumulate, i.e. count up. My Casio 150 watch has both a time accumulator (counts up) and a count down function - counts time downward from a max of 23h 59 min. You can set it for any time in hours and minutes down to one minute. I have not seen one of these devices like this Seiko that count down.

The clock is only visible when you push the Display button (only shows the time temporarily for a few seconds, then returns to displaying either the station frequency or file name of the music currently playing). The clock is 12-hour format only; there is no 24-hour standard time format available. From my experience with this unit, the built-in clock isn't extremely accurate. It's generally less than a minute off every month or so. For most people, this is good enough. Me personally, though? I'm glad the clock stays hidden by default because I have a clock mounted to my dash above the stereo.

Yes, you can count up and then stop. The time will start again at your command. This is not done in the timer mode but with the clock setting. If you needed to stop, time exactly a 30 sec time out then this is not what you need. However, if you needed to just stop the time counting up and begin again on command it will work.

I don't know about a counting-up feature, but the timers can be started and stopped independently. And the alarms are different too, so you know which one is chiming if the timing is close.

Yes! That's exactly what this one does. It skips ahead in increments of 30 seconds, and back in increments of 7 seconds. Very useful!

Yes! When it is used as an additive counter there is an "up" arrow displayed above the seconds. Of course it will only count up to 99:99:99.

No, it does not. It shows the seconds as well as the hours and minutes, though. But no clock feature.

No. It only keeps time for set intervals, it does not function like a clock.

I just tried to set it for a 24 hour countdown. The most I could do was 9:99:99. I don't know about a count up, but I imagine it would be similar.

I do believe that the item is always in timed mode. That way the student will know if they are getting faster at their answers. You can however turn off the sound by holding down the on off button for a second after you choose your level. I have not found a way to turn the timer off. Maybe they have improved on the original model.

Yes, there is a calculator function. It did not seem as easy to use as a regular calculator, but the functionality is there and I have not experimented with it very much. I don't really use it as it was bought for my wife, and she does not use it often (see my review on Amazon).

As far as we know, we have never tried to look for such a feature. It may be available. The Casio website has great tech support. Best suggestion would be to check there. Sorry we can't answer definitely.

No. You can only use it as a timer. If set on 0000 - it will count up. If set for 0500 - it will count down to 0. It is not a clock - it is just a timer.
