Bests & Worsts Reviews from Amazon

Back in the 1960s, homeroom elementary teachers taught longhand math (what is taught in schools today) and science teachers would teach quickhand math (aka shortcut/science math). Saw Brainetics tv ad this morning - me and spouse both said 'first time I've seen it in years'. We immediately recognized good ol' quickhand math, or science math. Remember Dad scribbling tax calc's and mom scribbling grocery and fabric yardage in the newspaper margins using quickmath? Same thing. In fact googlebooks has plenty of 1600's-1900's public domain science-history-math text books of elementary school instruction that include quickmath/science math (Full View too). Not a scam, not over-rated, not 'new' math, not cheater's math. The shock/scam online reviews of Brainetics appear groundless. They speculate, are ranting, frantic, suspicious, self-proclaimed non-user nay-sayers. Quickmath is old as dirt itself. An outcry over Brainetics' (one) BBB F-no reply rate is also humorous. The much-hyped issue is a nonreply, since BBB narrow codes don't have a N/A choice. BBB's edu industry/product no-review policy is clearly stated (on Brainetics' and all other BBB page). Anyway, anyone who knows math or uses it in their career would recognize Brainetics as good old fashioned scientific-math, just relabeled. But parents who prefer dumping a hundred dollars in the newest, most up-to-date, moderne, nouveau methods may not know better than to download a vintage googlebooks math text, or spend 5 to 10 bucks for a vintage school math book on amazon, ebay, or abebooks that'd teach the same thing. I personally miss the fun days of addiators, addometers, sliderules. It'd be terrific if schools would reintroduce science math. In other countries, both are taught. It is very fun to know both ways - and nice getting math done in one-third the time.
