Grade 1 Math Comparing Numbers
Comparing Numbers
Comparing
numbers between two numbers, we used 3 signs. They are-
a. Equal Sign (=)
b. Greater than sign (>)
c. Less than sign (<)
Equal/= is used to represent two equal quantities or numbers. such as:
4 = 4
or,
4 = 10 – 6
if a number is greater than another number, then we use greater than (>)
sign. such as:
6 > 5 [6 is greater than 5]
if a number is less than another number, then we use less than (<)
sign. such as:
3 < 4 [3 is less than 4]
Rules of comparing Numbers:
There are two rules to compare numbers. They are:
a. Numbers with more digits:
Example:
11 > 9 [9>1 but 11>9 because 11 has more digits than 9]
22 > 7 [22 has more digits than 7]
333 > 99 [333 has more digits than 7]
b. Numbers starting with a larger digit:
if both numbers contain the same digits then the number will be greater which
number leftmost places digit is greater.
Example:
99 > 89 [The first digit of 99 is greater than the first digit of 89]
323 > 313 [The second digit of 323 is greater than the second digit of
323]
