What is Ramanujan partition theory?
Ramanujan’s approximate formula, developed in 1918, helped him spot that numbers ending in 4 or 9 have a partition number divisible by 5, and he found similar rules for partition numbers divisible by 7 and 11. Without offering a proof, he wrote that these numbers had “simple properties” possessed by no others.
How do you explain partitioning to a child?
What is partitioning? When shown a number (up to 7+ digits by Year 6), children should be able to partition them independently to show good understanding of place value. For example, 5,202,086 = 5,000,000 + 200,000 + 2,000 + 80 + 6.
How do you add 2 digit numbers?
you can do this with math: a two digit number, 2 choices for the first digit, 2 choices for the second digit, so 2(2)=4; when you need to do a similar calculation with a longer digit number (or with more number choices), the second way is clearly better – for example, if you want to know how many two digit numbers you can make with the numbers 1, 2, 3, and 4, the answer is 4(4)=16 (this is easier than writing out all the combinations)
