Because - without even basic maths skills you wouldn't be able to do something as simple as buy a newspaper ! If you have no knowledge of maths at all - you wouldn't know (a) how much money to give the vendor and (b) whether they had given you the correct change !

What are some mathematical tricks?
Pick any number. Multiply by 6. Add 13. Subtract 7. Divide 3. Divide 2. Then subtract by the original number you chose. Your result will always be 1. Tell a friend to mentaly multiply their age by 2. Tell them to add 14 then divide 2. Ask your friend what number they currently have. Now, you mentally subtract 7 from the number they tell you, then you'll know your friend's age.

What are the order of operations mnemonic?
BODMAS = Brackets, Of, Divide, Multiply, [Add and Subtract]BODMAS = Brackets, Order, Divide, Multiply, [Add and Subtract]BODMAS = Brackets, Other, Divide, Multiply, [Add and Subtract]BIDMAS = Brackets, Index, Divide, Multiply, [Add and Subtract]I have bracketed Add and Subtract as when they are found together, they are done in the order they are found: from left to right.eg 1 + 2 - 3 is (1 + 2) - 3 and NOT 1 + (2 - 3) as the mnemonic would suggest.With Divide and Multiply, they can be done either left to right, or by doing the divide first, and the correct answer will be found, eg:2 x 6 ÷ 3 = (2 x 6) ÷ 3 = 2 x (6 ÷ 3)Note:6 ÷ 3 x 2 = (6 ÷ 3) x 2 ≠ 6 ÷ (3 x 2)But the last possibility would not be attempted as 'left to right' and 'divide first' are the same calculation (doing the division); showing that following strict 'DM' of BODMAS always works.My own creation: to get the sum correct, you will be under the watchful eye of the Bod Tsar:BODTSAR = Brackets, Of/Order/Other, Divide, Times, Subtract, Add (in order to get the) Result.Which fixes the slight imperfection that the B*DMAS don't show that the pairs of operations Divide & Multiply, and Subtract & Add have the same priority and are done in left to right order. However, if you always Divide before Multiplying (Timesing) and Subtract before Adding in those pairs, you will get the correct result, hence my mnemonic
