[quote=Anonymous][quote=Anonymous][quote]People keep saying that. But when I do math, I think in words.[/quote] Even if you are seriously challenged in math, I doubt this is true. [/quote] No, I'm not seriously challenged -- or maybe I am, but I nonetheless made it through various higher-level college math classes and work in a quantitative field. Here's a word problem I did with my child last night. "Ann sold 188 apples at the market on Wednesday. She sold 64 more apples in the afternoon than in the morning. How many apples did she sell in the afternoon?" Here's how we solved it: "OK, so Ann sold 64 more apples in the afternoon than in the morning. So in the afternoon, she sold the same amount of apples in the morning, plus 64. If I subtract 64 from 188, I get [do 188-64] 124 apples. Half of 124 is 62. So she sold 62 apples in the morning, and [do 62 + 64] 126 apples in the afternoon." (Or we could have, but didn't, say, "So she sold 62 apples in the morning, and [do 188-62] 126 apples in the afternoon." Is this not the right way to solve it? How would you solve it?[/quote]
