FAQs on 10 Maths Words That Start With A

1. What is the opposite of Ascending order?

The opposite of ascending order is descending order, which basically means to arrange the numbers or objects in decreasing order, that is, from the largest to the smallest. 

2. How can we determine the area of a square?

The area of a square can be measured by squaring its side length or multiplying its side length by itself. The unit will be square units.
