A multiplication table is a mathematical tool, in the form of a chart that conveys the product of two numbers. Usually, a table will be about any one number. That is if we want to write a table of 25, then in a distinct arrangement, 25 will be multiplied by one to ten. So the table will contain multiples of 25.
Multiplication means 'repeated addition. Multiplication tables (also known as the times' table) are memorized by students for the simplification of calculations. Studying multiplication tables will enhance your mental math ability and will speed up the process of multiplication.
The history of multiplication tables has a long path to go. The first multiplication table was first written by the Babylonians about 4000 years ago. They used 60 as a base. After that, the Chinese used 10 as a base in about 305 BC. They also used the decimal multiplication system.
To obtain a multiplication table, we have to multiply that number by consecutive natural numbers.
In numbers :
25×1 | 25 |
25×2 | 50 |
25×3 | 75 |
25×4 | 100 |
25×5 | 125 |
25×6 | 150 |
25×7 | 175 |
25×8 | 200 |
25×9 | 225 |
25×10 | 250 |
25×1 is read as twenty-five times one is twenty-five.
25×2 is read as twenty-five times two are fifty.
This is read in this way because multiplication is through repeated addition.
In words:
Twenty-five ones is | Twenty-five. |
Twenty-five twos are | Fifty. |
Twenty-five threes are | Seventy-five. |
Twenty-five fours are | Hundred. |
Twenty-five fives are | One hundred and twenty-five. |
Twenty-five sixes are | One hundred and fifty. |
Twenty-five sevens are | One hundred and seventy-five. |
Twenty-five eighths are | Two hundred. |
Twenty-five nines are | Two hundred and twenty-five. |
Twenty-five tens are | Two hundred and fifty. |
In this table, the one's place will always be zero or five.
Also, remember that this table will always end at 25, 50, 75, and 00. This will be so helpful in learning this table.
Twenty-five multiplied by twelve means twenty-five is added repeatedly twelve times.
So 25\times12=300\\25×12 =300.
The answer is 300.
Number of apples John eats per day = 3
Number of days John will eat apples = 25
Therefore, the total number of apples John will eat =
25\times3=75\\
25×3=75.
So the total number of apples he eats will be 75.
Number of days left for her exam = 25 days
Number of chapters she would revise daily = 5
Therefore the total number of chapters =
25\times5=125\\
25×5=125 chapters
\begin{aligned}
&26\times1=26 \\
&26\times2=52\\
&26\times3=78 \\
&26\times4 =104 \\
&26\times5 =130 \\
&26\times6= 156 \\
&26\times7 =182 \\
&26\times8 =208 \\
&26\times9 =234 \\
&26\times10=260 \\
\end{aligned}
If six people can travel in one car, then in 25 cars the number of people that can travel is
