Multiplication

Help on:(Multiplication Table 1-100)

Any number multiplied with zero is 0.

Ex: 5 x 0 = 0

100 x 0 = 0

Any number multiplied with 1 is the same number.

Ex: 5 x 1 = 5

345 x 1 = 345

Any number multiplied with 2 is just like doubling the number or adding the number two times.

Ex: 26 x 2 = 52 = 26 + 26

100 x 2 = 200 = 100 + 100

The following sheet gives the multiplication table of numbers from 0 to 10. One who memorizes the multiplication table can do multiplication of two digit, three digit, four digit numbers faster.

Online Indices

Onlne indices:

The ordered indices are as well acceptable for the numbers. For example, 54 is an archetype number. In this, the amount 5 is alleged the abject amount and the amount 4 is alleged as the power. From the aloft account we can aswell said the ability as the indices is artefact law, addition one is caliber law and the next one is ability law.

Product Law:

An archetype botheration for artefact law is accustomed below, They are

If accept p and s are absolute integers, again if b [!=] 0 means, again the artefact law is accustomed by,

Example: bp x bs = bp+s . This is archetype for the artifact law.

Quotient Law:

An archetype botheration for caliber law is accustomed below, They are

If accept p and s are absolute integers, again if b [!=] 0 means, again the artefact law is accustomed by,

bp [-:] bs = bp - s . This is archetype for the caliber law.

Power Law:

An archetype botheration for ability law is accustomed below, They are

If accept p and s are absolute integers, again if b [!=] 0 means, again the ability law is accustomed by,

( bp )s = bps . This is archetype for the ability law.

5th grade math problem:

Example issue 3:
What is the equivalent value of 5 3?
a) 15
b) 36
c) 125
d) 150
Solution:
5 3 = 5 to the power of 3.
This shows that two times the worth has to undergo multiplication.
Hence the 5 * 5* 5 = 125 or 5 3 = 125
Answer: 125

Hexagon problem

Hexagon dimensions

Find the surface area, base area, perimeter of base and volume of Hexagonal Prism whose apothem length 3cm, side 4cm and height 6cm.

Solution:

Given:

Apothem length (a) = 3cm

Side(s) =4cm

Height (h) =6cm.

Perimeter of base:

Perimeter of base (p) = 6s

= 6 x 4

=24 cm

Base area:

Base area (A) = 3as

= 3 x 3 x 4

= 36 cm2

Surface area:

Surface area = 6as + Ph

= 6 x 3 x 4 + 24 x 6

=72 + 144

= 216 cm2

Volume:

Volume (v) = Ah

= 36 x 6

= 216 cm3
