Welcome to the forum.

You have come to the right place. When you encounter a bit of algebra that you cannot understand, post the details here, and we will help you. I recommend you join as a member.

How are you with arithmetic? This might seem an odd thing to ask but it is relevant. The rules of algebra are the rules of arithmetic. When I'm teaching someone an algebraic topic I usually start by asking "How would we do this with numbers?"

There's also a wealth of pages plus practice questions here:

EXCEL is wonderful! I have used my equation H=3n2+3n+1 to calculate all the hexagons in the NESTED HEXAGONS and then this algorithm to identify the PRIME NUMBERS found in the H columns:

=IF(B9=2,"Prime",IF(AND(MOD(B9,ROW(INDIRECT("2:"&ROUNDUP(SQRT(B9),0))))<>0),"Prime","Not Prime"))

Place e.g. the algorithm in a cell opposite B9 and write in B9 and then CRL + SHIFT + ENTER in the address box to activate it.

Scroll down to include all the H cells and the list will read off the PRIME cells.

See: http://www.excelexchange.com/prime_number_test.html

I have competed 1000 NESTED HEXAGONS in pretty quick time with 3,003,001 elemental hexagons. The algorithm works up to 268,435,455 – I am NOT going to the limit!!

The PRIME NUMBER (P) hit ratio is steady diminishing and has reached ~1/4, having generated 254 P’s for 1000 NESTED HEXAGONS.

This exercise was fun but of what use?

Why the options are rainbow color only? Where are black, white, grey, pink, brown, and purple (slightly different than violet)?
