## What is the hardest problem in algebra?

For decades, a math puzzle has stumped the smartest mathematicians in the world. x3+y3+z3=k, with k being all the numbers from one to 100, is a Diophantine equation that’s sometimes known as “summing of three cubes.” When there are two or more unknowns, as is the case here, only the integers are studied.

**Is algebra a hard math?**

Algebraic thinking is not just arithmetic with letters standing for numbers. It is a different kind of thinking. Many people find arithmetic hard to learn, but most succeed, to varying degrees, though only after a lot of practice.

### Can 7th graders take algebra 1?

#### What is x3 y3 z3 K?

The equation x3+y3+z3=k is known as the sum of cubes problem. While seemingly straightforward, the equation becomes exponentially difficult to solve when framed as a “Diophantine equation” — a problem that stipulates that, for any value of k, the values for x, y, and z must each be whole numbers.
