18 * 21 = ?

Answer 1

Answer:

16 * 16 =26

23 * 33 =20

25 * 15 = 5

18 * 21 = 32

Answer 2

Answer:

The answer is 21

Step-by-step explanation:

• Given : 16 * 16 = 26

23 * 23 = 20

25 * 15 = 5

• To find : 18 * 21 = ?
• Solution :

16 - ( 16 - 16 ) x 1 + 0 = 16 [ here we are adding 0 because, we are getting 16 - 16 = 0, if the difference between two numbers are more than 0, then we have to add 3 ]

So, according to the format

33 - ( 33 - 23 ) x 1 + 3 = 20

15 - ( 15 - 25 ) x 1 + 3 = 28

21 - ( 21 - 18 ) x 1 + 3 = 21

So the answer is:

18 * 21 = 21
