You can also use an 8 times table and add natural numbers (multipliers) to the tens’ digit of its product to get a table of 18. Go through the table below to better understand this tip for memorizing 18 times table:
| Table of 8 | Generate the results of 18 times table | Table of 18 |
| 8 x 1 = 8 | (1+0) 8 = 18 | 18 x 1 = 18 |
| 8 x 2 = 16 | (2+1) 6 = 36 | 18 x 2 = 36 |
| 8 x 3 = 24 | (3+2) 4 = 54 | 18 x 3 = 54 |
| 8 x 4 = 32 | (4+3) 2 = 72 | 18 x 4 = 72 |
| 8 x 5 = 40 | (5+4) 0 = 90 | 18 x 5 = 90 |
| 8 x 6 = 48 | (6+4) 8 = 108 | 18 x 6 = 108 |
| 8 x 7 = 56 | (7+5) 6 = 126 | 18 x 7 = 126 |
| 8 x 8 = 64 | (8+6) 4 = 144 | 18 x 8 = 144 |
| 8 x 9 = 72 | (9+7) 2 = 162 | 18 x 9 = 162 |
| 8 x 10 = 80 | (10+8) 0 = 180 | 18 x 10 = 180 |
Question: If a group of students takes 18 days to complete a project, then how many days will they take to complete 5 such projects?
Solution:
Given that,
Days taken to complete 1 project = 18
Total number of projects = 5
Using table of 18,
⇒ 18 x 5 = 90
Thus, the students will take 90 days to complete 5 projects.
Question: What is the value of eighteen times of eighteen?
Solution:
Given that,
Eighteen times of eighteen
Mathematically it is written as,
⇒ 18 x 18 = 324
Hence, the value of eighteen times eighteen is three hundred and twenty-four.
Question: Find the number after 10 x 18 and before 8 x 18.
Solution:
10 x 18 = 180
Number after 180 = 180 + 1 = 181
And,
8 x 18 = 144
Number before 144 = 144 – 1 = 143
Hence, the number after 10 x 18 is 181, and before 8 x 18 is 143.
Question: By repeated addition, find the cost of 6 chocolates if the price of one chocolate is $18? (Use table of 18)
Solution:
Given that,
Cost of 1 chocolate = $18
Total chocolates = 6
By table of 18,
Cost of 6 chocolates = 6 x 18 = 108
Hence, the cost of 6 chocolates is $ 108.
Question: Find the value of 18 times 9 minus 21?
Solution:
Given that,
18 times 9 minus 21
In mathematical form,
= 18 x 9 – 21
= 342 – 21
= 321
Hence, the value of 18 times 9 minus 21 is 321
