Source document note: The official curriculum document has a fault in this entry, so the curriculum text above is transcribed exactly as printed:

indicator text - p.the document prints this indicator's code as B9.1.2.3.4 on printed p.171, but it prints no content standard B9.1.2.3 anywhere in B9; the standard cell beside it on the page is B9.1.2.4, whose own text ends 'determining (using a calculator) the approximate square root of a number that is not a perfect square', which is this indicator; and B9.1.2.4 runs .1 to .3, so .4 is the only free slot. Filed B9.1.2.4.4; the printed code was B9.1.2.3.4
