2857 14*3=857 142.。
This is a bit difficult to calculate. From the back to the front, it mainly starts from what is multiplied by 3 equals 2, so "Spring" is 4, which becomes: 20,000 purplish red 4*3= colorful red 42.
Then because 3*4 is equal to 12, the red color must be 1. It becomes: 20 thousand purple thousand 14*3= 142.
Consider that the number of units multiplied by 3 equals to 1 is only 7,7 * 3 = 21,so "thousand" is 7. Changed to: 20000 purple 7 14 * 3 = 20000 purple 7 142.
Since 7*3=2 1 has a "2", it is necessary to consider what times 3 equals (7-2) = 5, and only 5*3= 15, so "purple" is 5 and becomes: 25,765,438+04 * 3 =.
Since 5*3= 15, there is already a 1. Where the equal number is 5- 1 = 4, consider what is multiplied by 3 to equal the single digit is 4, and only 8 will become: 2857 14*3=857 142.
