In the most familiar acuity test, a Snellen chart is placed at a standard distance: 6 metres.
Placing a somewhat closed right hand on the plane with the thumb pointing up, the fingers point from the x-axis to the y-axis, in a positively oriented coordinate system. The other way of orienting the plane is following the left-hand rule, placing the left hand on the plane with the thumb pointing up.

The concept of the complex plane allows a geometric interpretation of complex numbers. Under addition , they add like vectors . The multiplication of two complex numbers can be expressed most easily in polar coordinates — the magnitude or modulus of the product is the product of the two absolute values , or moduli, and the angle or argument ...
