[quote=Anonymous][quote=Anonymous][quote=Anonymous]both ends of an equal sign have to be equal with or without space. Period. I'm sorry to tell you that math expressions should be more rigorous and formal than what you say in everyday life. [/quote] And yet Singapore Math has expressions like 65 - 10 [fill-in-the-blank] - 2 [fill-in-the-blank] as a mental math strategy for 65-12.[/quote] depends what's in the blank It's perfectly fine to have 65-12 = 65 - 10 - 2 = 55 - 2 = 53 big mess if 65 - 12 = 65 - 10 = 55 - 2 = 53 I won't use that book to teach math.
