Ramanujan results for middle school?

Pls I wonder what Ramanujan's results could be explained to middle school level audience, ie without using integral etc that is up to university curriculum?

For example Ramanujan's infinite radicals could be explained easily

$$3=\sqrt {1+2{\sqrt {1+3{\sqrt {1+\cdots }}}}}$$

• just his results have many infinite forms, which sound fun! @ChrisCunningham Jul 18 '20 at 12:54

• The number of partitions of $$n$$ in which adjacent parts are at least 2 apart is the same as the number of partitions of $$n$$ in which each part ends with 1,4,6,9.
• The number of partitions of $$n$$ without 1 in which adjacent parts are at least 2 apart is the same as the number of partitions of $$n$$ in which each part ends with 2,3,7,8.
For example, taking $$n=10$$:
• Partitions in which adjacent parts are at least 2 apart: $$10 = 10 = 9 + 1 = 8 + 2 = 7 + 3 = 6 + 4 = 6 + 3 + 1$$
• Partitions in which each part ends with 1,4,6,9: $$10 = 9 + 1 = 6 + 4 = 6 + 1 + 1 + 1 + 1 = 4 + 4 + 1 + 1 = 4 + 6\times 1 = 10 \times 1$$
• Partitions without 1 in which adjacent parts are at least 2 apart: $$10 = 10 = 8 + 2 = 7 + 3 = 6 + 4$$
• Partitions in which each part ends with 2,3,5,8: $$10 = 8 + 2 = 7 + 3 = 3 + 3 + 2 + 2 = 2 + 2 + 2 + 2 + 2$$
