パンサー尾形貴弘が数学の難問を大真面目に解説する「笑わない数学」。テーマは「無限個のたし算」。数学者なのに厳密さにとらわれない（？）意外で大胆な計算が連発！
１＋２＋３＋４＋…と無限につづく数を全部たしあわせた答えは？ テストでそう問われたら正解は無限大（答えなし）。ところが数学者が作り出したある理論をつかうと、答えはなんとマイナス１２分の１になるという。なぜこんな信じられない計算が成り立つのか！？ 歴史上の数学者たちは、無限個のたし算に出会って以来、その奇妙さに困惑しつづけてきた。宇宙の自然法則につながる隠された意味があるという驚きの話も紹介！
"Mathematics without laughing" in which Takahiro Ogata explains the difficult problems of mathematics seriously. The theme is “infinite counting.” He is a mathematician, but he is not strictly bound by it (?) Unsurprisingly, a bold calculation is made!
What is the answer to 1+2+3+4+... and all the infinite numbers? If you ask me on the test, the answer is infinite (no answer). However, if you use a theory created by a mathematician, the answer is minus twelve-tenths. Why is this such an unbelievable calculation? Since the mathematicians of history have encountered infinite numbers, they have been puzzled by its strangeness. We also introduce a surprising story that there is a hidden meaning that leads to the natural laws of the universe!
