# Three Digits | What is Spike Abacus? Three-digit numbers are from 100 to 999. We all know that there are 9 single-digit numbers, particularly 1, 2, 3, 4, 5, 6, 7, 8, and 9. There are 90 two-digit numbers, i.e. from 10 to 99. Single digit numbers are made with the numbers 1, 2, 3, 4, 5, 6, 7, 8 and 9. When making two-digit numbers, zero (0) is used along with the numbers from 1 to 9. two-digit numbers, the place one digit represents the variety of ones and the opposite the variety of tens.

The digit representing ones is positioned within the ones place, and the digit representing them is positioned within the tens place. As in 52, 5 is 5 × 10 = 50 within the tens place and a pair of is 2 × 1 = 2 within the ones place.

Equally5 out of 35 is 5 × 1 = 5 within the ones place and three × 10 = 30 within the 3 tens place so 35 = 30 + 5.

The primary twelve digit numbers include the numbers 0, 1, 2, …. It comes after 1, ie 10, 11, 12, 13, 14, 15, 16, 17, 18 and 19. Then comes 2 within the tens place. All digits come after 2 i.e. 21, 22, 23, 24, 25, 26, 27, 28 and 29.

The desk beneath exhibits the formation of two-digit numbers:

Sophia has 99 beads. It makes use of 10 beads to make 1 wreath. She made 9 wreaths she and now she has 9 beads left.

99 = 9 dozens and 9 those that

He takes 1 extra bead from his mom. Now she will be able to make one other garland of 10 beads.

The full variety of beads is now 100.

99 and 1 extra is 100

Ninety-nine and yet one more is 100.

The quantity counted after 99 is 100. It is a three digit quantity. Including one to 99 makes a complete of 100.

There are 10 tens or 100 ones in 100, so (100 = 10 × 10 = 100 × 1). With the assistance of ones, we get two-digit numbers from 10 to 99 with the assistance of tens, ones and tens.

we all know that

one ten = entrance (10)

two tens = twenty (20)

three tens = thirty (30)

4 tens = forty (40)

5 tens = fifty (50)

six ten = sixty (60)

seven ten = seventy (70)

eight ten = eighty (80)

9 ten = ninety (90)

ten = face (100)

Equally,

1 × face = face (100)

2 × face = two faces (200)

3 × face = 300 (300)

4 × face = 4 hundred (400)

5 × face = 5 hundred (500)

6 × face = 600 (600)

7 × face = seven hundred (700)

8 × face = eight hundred (800)

9 × face = 9 hundred (900)

10 × hundred = thousand (one thousand)

We see that three-digit numbers equivalent to 100, 200, 300, 400, 500, 600, 700, 800 and 900 are represented by digits with one digit and two zeros. These numbers are multiples of two numbers, i.e. 100×1, 110×2, 100×3, …….., and so on.

Nevertheless, three-digit numbers are fashioned by inserting the one and two-digit numbers from 1 to 99 as 101, 102, 103, 104, 105, 106, respectively, after the essential digits 1, 2, 3, ….., 9. , 107, 108, 109, 110, ……., 117, 118, 119, ………, 125, 126, 127, …….., 134, 135, 136, ……….., 299, 300, 301, ….…., 400, ….…, 427, ………….and so on.

In three-digit numbers, the digits are positioned within the ones, tens and tons of place. There’s those digit on the far proper of the quantity, the tens digit on the left, and the tons of digit on the left. Numbers have a sure variety of place values.

For instance, In 235, the place worth of 5 is 5, the place worth of three is 30, and the place worth of two is 200. 2 hundred thirty 5.

Let’s create the quantity 100 with the assistance of blocks. If we are saying a small block 1, then a strip of 10 small blocks represents 10. A sheet of 10 strips exhibits 100.

It may be simply defined with the assistance of mathematical units known as three-digit numbers. ABACUS.

### What’s a spike abacus?

The spiked abacus has a number of iron nails on a wood base. The spikes can have globules, that are wholes. The spikes are ones, tens, tons of, 1000’s, and so on., from proper to left, respectively. known as.

The variety of globules within the respective spines represents the place worth of the digit of the quantity. The abacus image given has three spikes. There are 2 globules within the first spike that denotes ones, 3 globules subsequent to it, and 4 globules within the third spike from those’ spike.

The signal of two globules one, spike 2 × 1 = 2, 3 globules specific tens of spikes 3 × 10 = 30, whereas 4 globules specific third spike, ie tons of of spikes 4 × 100 = 400. represents the quantity 400 + 30 + 2 = 432 in other places.

Thus, with the assistance ofabacusFrom , we will perceive the idea of a three-digit quantity.

Evaluation:

A quantity has a number of digits.

We use the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 to write down numbers.

Single digit numbers equivalent to 1, 2, 3, ………… 9 are known as single digit numbers.

Double-digit numbers equivalent to 22, 53, 67, …… 99 are known as two-digit numbers.

Three-digit numbers equivalent to 100, 235, 367, …… 999 are known as three-digit numbers.
