Three digit numbers are from 100 to 999. We all know that there are 9 one-digit numbers, i.e., 1, 2, 3, 4, 5, 6, 7, 8 and 9. There are 90 two digit numbers i.e., from 10 to 99. One digit numbers are made by the digits 1, 2, 3, 4, 5, 6, 7, 8 and 9. In making two digit numbers, zero (0) can be utilized together with digits 1 to 9. In two digit numbers one digit represents variety of ones and the opposite signify the variety of tens.

The digit representing ones is positioned at one’s place whereas the digit representing ten’s is positioned at ten’s place. As in 52, 5 is at ten’s place having its worth 5 × 10 = 50 and a pair of is at one’s place having it’s worth 2 × 1 = 2.

Equally, in 35, 5 is at one’s place having it’s worth 5 × 1 = 5 and three is at ten’s place having its worth 3 × 10 = 30 i.e., 35 = 30 + 5.

Within the first ten two digits numbers the digits 0, 1, 2, …. are positioned after 1 i.e., 10, 11, 12, 13, 14, 15, 16, 17, 18 and 19. Then comes 2 at ten’s place. All of the digits are positioned after 2 i.e., 21, 22, 23, 24, 25, 26, 27, 28 and 29. 

The next desk reveals the formation of two digits numbers:

Sophia has 99 beads. She makes use of 10 beads to make 1 garland. She has made 9 garlands and now she is left with 9 beads.

99 = 9 tens and 9 ones

She will get 1 extra beads from her mom. She is now in a position to make one other garland of 10 beads. 

The full variety of beads now 100.

99 and 1 extra make 100

Ninety-nine and another make 100.

What comes after 99?

The quantity is 100. It’s written in phrases as 100. It
is a 3-digit quantity.

We will say that ninety-nine and another = 100.

Utilizing tens, we are saying that 10 tens = 1 hundred.

So, after 99, the counting quantity is 100. This can be a three digit quantity. When one is added to 99, the sum is 100.

In 100, there are 10 tens or 100 ones, i.e., (100 = 10 × 10 = 100 × 1). With the assistance of ones we get tens and with the assistance of ones and tens we make the numbers of two digits, i.e., from 10 to 99.

We all know that

  One ten = ten (10)

  Two tens = twenty (20)

  Three tens = thirty (30)

  4 tens = forty (40)

  5 tens = fifty (50)

  Six tens = sixty (60)

  Seven tens = seventy (70)

  Eight tens = eighty (80)

  9 tens = ninety (90)

  Ten tens = 100 (100)

Equally, 

  1 × hundred = hundred (100)

  2 × hundred = 2 hundred (200)

  3 × hundred = 300 (300)

  4 × hundred = 4 hundred (400)

  5 × hundred = 5 hundred (500)

  6 × hundred = 600 (600)

  7 × hundred = seven hundred (700)

  8 × hundred = eight hundred (800)

  9 × hundred = 9 hundred (900)

10 × hundred = ten hundred (1000)

We see that the three digit numbers like 100, 200, 300, 400, 500, 600, 700, 800 and 900 are represented by the numerals having a digit and two zeros. This numbers are the multiples of two numbers i.e., 100 × 1, 110 × 2, 100 × 3, …….., and so forth.

However the three digit numbers are shaped by putting the one and two digit numbers, i.e., from 1 to 99 after the elemental digits 1, 2, 3, ….., 9 respectively as 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, ……., 117, 118, 119, ………, 125, 126, 127, …….., 134, 135, 136, ……….., 299, 300, 301, ….…., 400, ….…, 427, ………….and so forth.

In three digit numbers the digits are positioned at one’s, ten’s and hundred’s place. On the excessive proper of the quantity there may be one’s place, then to the left of it there may be ten’s place and to the left of it there may be hundred’s place. The digits have their place worth in a given quantity.

For instance, in 235 the place worth of 5 is 5, of three is 30 and a pair of is 200. We write this in phrases as 2 hundred thirty 5.

Allow us to type the quantity 100 with the assistance of blocks. If we are saying one small block is 1 then a strip manufactured from 10 small blocks will signify 10. A sheet manufactured from 10 strips will present 100.

The three digits numbers might simply be defined with the assistance of mathematical equipment known as ABACUS.

What’s spike abacus?

Spike abacus has many iron spikes on a wood base. The spikes might have globules having wholes. The spikes are named as ones, tens, lots of, hundreds and so forth. respectively from excessive proper to the left.

The variety of globules within the involved spikes expresses the place worth of the digit of the quantity.

Within the given image of the abacus, there are three spikes. Within the first spike expressing ones, there are 2 globules, subsequent to it there are 3 globules and within the third spike from those’ spike there are 4 globules.

2 globules of the one’s mark, spike categorical 2 × 1 = 2, 3 globules of the tens spike categorical 3 × 10 = 30 whereas 4 globule of the third spike i.e., lots of spike categorical 4 × 100 = 400. Thus, the globules positioned at completely different locations signify the quantity 400 + 30 + 2 = 432.

Thus, with the assistance of ‘abacus’ we will perceive the idea of three digit numbers.

Assessment:

● A quantity has one or multiple digit.

● To jot down the numbers we use digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

● A quantity which has single digit like 1, 2, 3, …………. 9 are known as one digit numbers.

● A quantity which has double digits like 22, 53, 67, …………… 99 are known as two digits quantity.

● A quantity which has triple digits like 100, 235, 367, …………… 999 are known as three digits quantity.

● To learn a two-digits quantity, first learn the tens place after which learn those place.

● To learn a 3 digits quantity, first learn the lots of place, then learn the final two digits as proven under.
