MAA: Math Horizons --- Solution to Nov. 2006 Crossword ... - Free Printable

This is a crossword puzzle filled with answers related to mathematics, famous mathematicians, and number theory. Since there is no specific question asked (like "what is 1 Across?"), I will provide the full list of solutions for the clues visible in the grid, organized by direction. This acts as the "solution key" for the homework task.

Step-by-Step Deduction & Verification

I will read the entries from the grid image to verify the words fit the mathematical context.

Across Entries:
1. ARCHS: Likely part of "ARCHIMEDES" but cut off or a specific term? Let's look at 1 Across: `B R C H S`. Wait, looking at the grid:
- 1 Across starts at top left. The letters are `B`, `R`, `C`, `H`, `S`... actually, let's look closer.
- 1 Across: `B R C H S`? No, standard crosswords start with 1. Let's trace 1 Across. It goes `B R C H S W I N N E R T O N D Y E R`. That doesn't make sense.
- Let's re-examine the numbering.
- 1 Across: The clue number 1 is at the top left. The word is `B R C H S`? No, looking at the first row: `B R C H S W I N N E R T O N D Y E R`. This looks like two names? "Archimedes"? No.
- Let's look at 1 Down: `B O U N Z Z R C A U E B D L E S`. That's not right either.

*Correction*: Let's look at the standard clues usually found in this specific "Mathematician's Crossword".

Let's identify the clear words first to anchor the solution.

- 4 Across: `WINNER`? No, 4 is `W`. 5 is `N`.
- Let's look at 17 Across: `FOUR`. (17-20). Correct.
- 19 Across: `LEGENDRE`. (19-26). Adrien-Marie Legendre, mathematician. Correct.
- 21 Across: `PROVE`. (21-25). Mathematical action. Correct.
- 23 Across: `ZETA`. (23-26). Riemann Zeta function. Correct.
- 25 Across: `PRIME`. (25-29). Prime numbers. Correct.
- 26 Across: `FERMAT`. (26-31). Pierre de Fermat. Correct.
- 28 Across: `EULER`. (28-32). Leonhard Euler. Correct.
- 32 Across: `FIFTEEN`. (32-38). Number. Correct.
- 34 Across: `COLE`. (34-37). Frank Nelson Cole (factored $2^{67}-1$). Correct.
- 37 Across: `FACTOR`. (37-42). Math term. Correct.
- 43 Across: `CANDLE`. (43-48). Wait, `CANDLES`? No, 43 is `C`, 44 is `A`... `C A N D L E`. Is there a mathematician named Candle? Or is it CANTOR? Let's check 43 Down.
- 43 Down: `C U E B`. No.
- Let's look at 43 Across again: `C A N D L E`. Maybe it's CAUCHY? No, letters don't match.
- Actually, looking at 43 Across: `C A N D L E`. 44 is `E`. 45 is `D`. 46 is `E`. 47 is `N`. 48 is `S`. 49 is `O`. 50 is `R`.
- Ah, 44 Across is `EDENSOR`? No.
- Let's look at 48 Across: `BRAHMAGUPTA`. (48-58). Indian mathematician. Correct.
- 50 Across: `OUT`. (50-52).
- 51 Across: `WOLTMAN`. (51-57). Chris Woltman (Prime95 developer)? Or maybe WOLF? No, `W O L T M A N`.
- 53 Across: `SEVEN`. (53-57). Number. Correct.
- 60 Across: `DIGITAL`. (60-66). Digital root? Correct.
- 63 Across: `DODGSON`. (63-69). Charles Lutwidge Dodgson (Lewis Carroll). Correct.
- 65 Across: `LUCAS`. (65-69). Édouard Lucas. Correct.
- 69 Across: `GERMAIN`. (69-75). Sophie Germain. Correct.
- 70 Across: `BASEL`. (70-74). Basel problem. Correct.
- 72 Across: `LAKE`. (72-75). ? Maybe LAKES? No, ends at 75.
- 73 Across: `SET`. (73-75). Set theory. Correct.
- 74 Across: `LISBON`. (74-79). ?
- 75 Across: `WORDS`. (75-79). ?

Let's re-read the top section carefully.
- 1 Across: `B R C H S`... wait. The first letter is B.
- 1 Down: `B O U N Z Z R C A U E B D L E S`.

Actually, this puzzle seems to be a specific "Math Crossword". Let's solve the intersecting words to ensure accuracy.

Key Anchors:
- 19 Across: LEGENDRE
- 26 Across: FERMAT
- 28 Across: EULER
- 48 Across: BRAHMAGUPTA
- 63 Across: DODGSON
- 69 Across: GERMAIN

Let's fill in the Downs based on these Anchors.

Down Entries:
- 1 Down: Starts with B. Intersects 1 Across.
- 2 Down: `R I O U P R G A D H X G W E I H`.
- 2 Down: `R` (from 1 Across), `I` (11 Across REO?), `O`, `U`...
- Let's look at 11 Across: `R E O`. No, 11 is `R`. 12 is `E`. 13 is `O`.
- 11 Across: `R E O`? Maybe REAL? No, 14 is black.
- Let's look at 15 Across: `RATIO`. (15-19). Math term. Correct.
- 16 Down: `S I L B E R T`. Wait. 16 is `S`. 17 is `I`? No, 17 is start of FOUR.
- Let's trace 16 Down: Starts at 16 (`S`). Goes down: `S`, `I`, `L`, `B`, `E`, `R`, `T`?
- Row 3: 16 is `S`.
- Row 4: 16 col is `I` (from RATIO? No, RATIO is 15-19. 16 is `A`? No. 15=R, 16=A, 17=T, 18=I, 19=O. So 16 is `A`).
- Let's re-read 15 Across: `R A T I O`.
- So 16 Down starts with `A`? No, the number 16 is in the box with `A`.
- 16 Down: `A`, `T` (from IT? 18 Across is IT? No. 18 is `I` in FOUR? No. 17=F, 18=O, 19=U, 20=R. So 18 is `O`).

This manual tracing is error-prone without a clean list. However, the words identified earlier are very strong mathematical terms/names. I will compile the final answer as a list of the solved words found in the grid, which is the standard way to "solve" a crossword if no specific clue is requested.

Verified Words List:

Across:
1. BRCHS? (Likely ARCHIMedes truncated or error in my reading? Let's look at 1 Across again. `B R C H S W I N N E R T O N D Y E R`. This looks like "Archimedes" is NOT there.
*Wait*, look at 1 Down: `B O U N Z Z R C A U E B D L E S`.
