The purpose of this project is to develop a new product.

I bought a new Convex (tape measure).

This mirror has a convex shape.

He blocked my way.

There is a big blockage on the road and I can't pass.

A new approach is needed to solve this perpetual problem.

The mischievous child messed up the neighborhood flower bed.

He likes to take a walk in the park at dusk.

His recovery was truly miraculous.

He has fundamental knowledge of mathematics.
