مسطرة مع آلة حاسبة مدمجة

The calculator is surprisingly responsive for such a slim device, and the ruler itself is crystal clear with precise markings. It fits perfectly in my pencil case for school.

I'm not great at mental math, so having a calculator built right into my ruler is a total game changer for my drafting projects. The whole thing is surprisingly lightweight and fits perfectly in my pencil case.

Was pleasantly surprised how smoothly the calculator buttons work even with the ruler being so thin. Handy to have both tools in one, especially when I'm doing quick measurements and math on the go. The clear plastic is sturdy enough to last in my pencil case.
