I order a 9-inch Pizza but out of stock, the shop gives me 2 Pizzas of 5-inch instead, still at the same price, saying the extra 1 inch is free of charge.
Do I gain or lose ?
[Hint]: Do not scroll further down, till you revise the Primary school Math.
Answer: 10 (Yes!) but why ?

[Original Financial Times Article] Google: UK maths books fail DfE test
UK, USA, France are copying Chinese Math (from which the “Singapore Modeling Math” derived) in Primary schools, this proves my above-mentioned “Ideal Math” formula is correct. The 2 Asian countries were top in 2015 PISA Math Test for 15-year-old students, while UK was ranked 27th.
It remains to see if China / Singapore reciprocate the French Math theoretical foundation rigor in High Schools (Junior Colleges) and in the first 2 years of undergraduates for STEM (Science, Technology, Engineering, Math) students.
Compared with Fields Medals (equivalent to Nobel Prize in Math), the picture is reversed – where USA, France and UK are top. The secret lies in the formula : the multiplying factor – (* French), ie the math theoretical foundation notably in French Math.
Note: 2 Chinese Fields Medalists are listed in the nationalities of “British / HK, now China” (ST Yau 丘成桐), Australia (Terence Tao 陶哲轩 ).
