Under order of operations,
Under order of operations, errors can be made with the instructions here: 12 / 3 x 2 + 20 / 5 x 2 should yield 8 + 8 or 16, but some students might get the following 2 + 2 or 4. Why did they get this wrong answer? They do all multiplications first and return to left to do divisions. GEMA is a better method, see the book "Math in Words" by George P Bullock. Read the section titled: "The Real Order of Operations: GEMA". G-grouping symbols, E-exponent operations, M - multiplication operations which include division, and A - addition operations which includes subtraction. It is time to put PEMDAS to "RIP"!

This is a brilliant resource with a variety of uses, it is basically a set of posters on all sorts of areas of Mathematics. It is in black and white so could be printed and copied as a set of revision notes for students. I would probably print these on to colored paper and display around the classroom as a visual cue for students. This must have taken a long time to produce, thank you for sharing.
