In this chapter, we learn to count objects beyond 200 as earlier using the same number names and comparing the numbers.
Comparing and Ordering Numbers
Comparing and ordering numbers is to compare the numbers according to their values and identify the smallest and greatest numbers and order them in smallest to greatest and greatest to smallest.
Use of Less than (<) and Greater than (>)
The less than (<) and greater than (>) symbols are used to compare given two numbers. A greater number greater than a smaller number is represented as
Greater Number > Smaller Number.
e.g.
274 > 143
A smaller number less than a greater number is represented as
Smaller number < Greater number.
e.g.
374 < 474
