Numbers up to 2-Digits In 2-digit numbers, there are only two place values - the units place and the tens place. Every number which has more than 1-digit has different digits described by their place values. 2-digit numbers start from 10 and end on 99. In other words, the smallest 2-digit number is 10 and the greatest 2-digit number is 99. 1. 2. 3. 4. What are 2-Digit Numbers? 2-digit numbers are the Place Value in 2 Digit Numbers Assigning Place Values We know that the place value of a number tells the position of the digit. In 2-digit numbers, tens and ones are the only place values. Let us look at the following set of numbers to understand the combination of ones and tens: a.) 33 ⇒ 3 tens + 3 ones = (3 × 10) + (3 × 1) = 30 + 3 = 33 b.) 18 ⇒ 1 tens + 8 ones = (1 × 10) + (8 × 1) = 10 + 8 = 18 c.) 27 ⇒ 2 tens + 7 ones = (2 × 10) + (7 × 1) = 20 + 7 = 27 How to Write Numbers up to 2-Digits? 2-digit numbers can be written in the numeral form, in words, and in the expanded form. For example, 45 is a 2-digit number. Let us see the three ways in which it can be written. • In the numeral form: 45 • In words: Forty-Five • In the expanded form: 40 + 5 2-Digit Numbers in Words When numbers are written in words with the help of the place values, it helps us to spell them. The smallest 2-digit number is 10 which is written as ten. After this, the numbers from 11 to 20 are written as 11 - eleven,12 - twelve, 13 - thirteen, 14 - fourteen, 15 - fifteen, 16 - sixteen, 17 - seventeen, 18 -...

SOLUTION: A number consists of two digits. The sum of the digit is 10. On reversing the digits of the number, the number decreases by 36. What is the product of the two digits ? SOLUTION: A number consists of two digits. The sum of the digit is 10. On reversing the digits of the number, the number decreases by 36. What is the product of the two digits ? You can A number consists of two digits. let a = the tens digit let b = the units then 10a+b = the "number" : The sum of the digit is 10. a + b = 10 : On reversing the digits of the number, the number decreases by 36. 10b + a = 10a + b - 36 Combine like terms 10b - b = 10a - a - 36 9b = 9a - 36 simplify, divide by 9 b = a - 4 -a + b = -4 : use elimination on the two equation a + b = 10 -a + b = -4 ------------------addition eliminates a, find b 2b = 6 b = 3 You should be able to find a, and check that it satisfies the the statement "On reversing the digits of the number, the number decreases by 36. " then answer the question " What is the product of the two digits ?"
