### Large Type and Talking Five Function Calculators and Applied Math

**A parent writes:***I'm trying to find other options for my son in computing math problems. He is a sophomore this year and is taking applied math. He has visual impairment due to saccadic eye movements. He also has involuntary muscle movements. Fine motor skills are very difficult, if not impossible. Can anyone suggest a calculator that would work for him? For instance, are there portables with enlarged keys that repeat entries with speech synthesis...AND are easy to use? Any suggestions would be appreciated*

**Susan replies: **Since your son is taking applied math, I would recommend a five function (+, -, *, /, %) talking calculator. There are several models and prices and various vendors. I will give you a list to choose from, but there may be other sources closer to home where you can find bargains. The calculators described in depth below are the ones I have successfully used with those of my applied math students who had great difficulty with talking calculators having small keys and compact keypads.

They have a talking desktop calculator with a large 8 digit LCD readout, a repeat key, and enlarged keys for $18.95 (with earphone $28.95). They have quite a variety of other talking and/or large number calculators as well.

The Lighthouse Inc.
