An individual may have difficulty recognizing or identifying numbers, remembering sequencing of numbers, understanding the mathematical sign or function (whether symbol or word) or performing mathematical calculations accurately and efficiently.  Other tasks that may be problematic include being able to count, tally, measure, or track due to an inability to “do math” or perform calculations involving numbers.


Construction calculators assist with completing layouts, plans, bids, and estimates. They also calculate circles, roofs stairs, and more. Construction calculators are great for converting between feet-inches-fractions and decimals, including metric.
