This question can't be answered as asked because IXX isn't valid in any known numbering system. The nearest valid number is XIX in the Roman system, or 19 in our system. Showing my working is not possible because it was done in my head. If you want to know how you could do it in your head (or on paper if you need to show it to your teacher) here it is. * XIXII can be re-written as XXII - (II x XIX) - I. * XXII = CD * - (II x XIX) - I = - XXXIX * CD - XXXIX = CCCLXI * XIXII = CCCLXI . . . . .

What is IXX squared showing all your working?
IXX (19) squared = -I(-I+XX)+XX(-I+XX) Multiplying out brackets = +I-XX-XX+CCCC Collecting like terms = -XXXX+CCCC+I (401-40) Then when simplified = CCCLXI (361) which is the correct answer. Remember that in maths a minus number multiplied by a minus number produces a plus number. Thus -I times -I is +I. David Gambell, Merseyside, England.
How do you multiply 19 by 19 using roman numerals?
First of all today we write out 19 in Roman numerals as XIX but the Romans themselves would have probably calculated 19 as XVIIII and then simplified it to IXX in fact the Latin word for IXX is 'undeviginti' which literally means one from twenty. So the question is: What is IXX squared? IXX squared = -I(-I+XX)+XX(-I+XX) Multiplying out the brackets = +I-XX-XX+CCCC Collecting like terms = -XXXX+CCCC+I (401-40) When simplified = CCCLXI (361) which is the answer to your question. Note that in maths a minus number multiplied by a minus number becomes a plus number. Thus -I times -I is +I.
Convert steel ixx values to aluminum ixx?
To convert the second moment of area (Ixx) from steel to aluminum, you can use the ratio of their modulus of elasticity (E). The ratio of E for steel to aluminum is approximately 3:1. Multiply the steel Ixx by 3 to get an estimate of the equivalent Ixx value for aluminum.

How do you square 19 in Roman numerals?
Due to rules made during the Middle Ages, today we write out 19 in Roman numerals as XIX. But the Romans themselves would have probably wrote out 19 as XVIIII and then simplified it to IXX. In fact the Latin word for 19 is "undeviginti" which literally means one from twenty. Hence: IXX*IXX = -I*IXX + XX*IXX = +I-XX-XX+CCCC = CCCLXI (361) In Hindu-Arabic numerals: -1(-1+20) + 20(-1+20) = +1-20-20+400 = 361
