So this is why you MUST NOT arbitrarily add multiply signs to Terms (which a lot of people do!). If you do, you can change the answer. Single Terms are inseparable. A VERY common mistake is to say that 2(4)=2*4. No, it isn't! It's equal to (2*4). You CANNOT remove the brackets until there is only a single Term left inside them. i.e. 8. Also, because (2*4) is inside brackets, this is, as per earlier meme, part of "B" in BEDMAS, not "M" - there is no multiply sign outside brackets! More next week

    1/4 #MathsMonday Now we'll tie the previous 2 #Math rules together and see why #Mathematics order of operations means #MathsIsNeverAmbiguous provided you #DontForgetDistribution Start with 1, also the result of any number divided by itself, so let's write 8/8 We can factorise, and 8 is even, so let's take out a 2, 8/2(4) We can rewrite the stuff in brackets without changing the answer, so let's write 8/2(1+3) I started with 1,so we have to make sure the rules of #Maths get us back there...
