What fills a 25x25 multiplication chart
A multiplication chart up to 25 has 625 squares, and 225 different answers fill them. Five answers share first place with 8 squares each: 24, 48, 60, 72 and 120. Five answers in the tinted row are square numbers, 25, 100, 225, 400 and 625, because 25 is 5 × 5.
Reading a multiplication chart 1 to 25 in quarters
Four 25s make 100, so count the tinted row like coins. 25 × 12 is 12 quarters, 3 dollars, 300. 25 × 13 is one more quarter, 325. Every answer in the row ends in 00, 25, 50 or 75, so a filled-in square there that ends any other way is wrong.
- 24 × 25 is easier than it looks: 24 quarters are 6 dollars, so the answer is 600.
- Halve one number and double the other: 25 × 18 is the same as 50 × 9, which is 450.
Questions and answers
Is a multiplication chart 25x25 the same as a 25 x 25 multiplication chart?
Yes, the same chart typed two ways. Rows and columns run from 1 to 25 and the last square is 25 × 25 = 625. A multiplication chart 1 25, written without the dash, is that chart too.
What is a multiplication chart of 25?
It usually means the 25 times table alone: 25, 50, 75, 100 and on up to 625. Here that is the tinted row, and its 25 facts are listed further down. The note on 25 × 20 = 500 says twenty quarters make 5 dollars.
How many facts are on a multiplication chart to 25?
625 squares, but 325 facts once 7 × 9 and 9 × 7 count as one. A 12 by 12 chart covers 78 of them, so the rows from 13 to 25 add 247 facts that are new.
Why does the 25 row feel easier than the 24 row?
Because 25 is a quarter of 100. Multiply by 100, then cut the answer into 4 parts: 25 × 16 is 1,600 cut in 4, or 400. The 24 row leans on its neighbor: 24 × 16 is 400 minus one 16, or 384.
