Affordances of fractions and decimals for arithmetic.
Journal of Experimental Psychology: Learning, Memory, and Cognition, 2023 Rational numbers are represented by multiple notations: fractions, decimals, and percentages. Whereas previous studies have investigated affordances of these notations for representing different types of information (DeWolf et al., 2015; Tian et al., 2020), the present study investigated their affordances for solving different types of arithmetic ...

Some integer formula-encodings and related algorithms [PDF]
, 2013 We investigate the special class of formulas made up of arbitrary but finite com- binations of addition, multiplication, and exponentiation gates. The inputs to these formulas are restricted to the integral unit 1.
