👉 In mathematics, a sufficient condition is a condition that must be met for a certain event to occur. It's like having a piece of paper and knowing that you need it to do your homework. If you don't have the paper, you won't be able to complete your assignment. This is similar to saying if you have a box of crayons and know that you need at least one more crayon for your project, then you can start with the first crayon in the box.
