Mathematics, how to change the number 4 12 from decimal number to decimal number?
An easier way to understand is to convert it to decimal and then to hexadecimal.

(4 12) Five =4×5? 0? 5+ 1×5+2= 107

Then use short division,

107÷7= 15……2

15÷7= 2…… 1

2÷7= 0 ……2

The remainder is 2 12 (hexadecimal) in descending order.

In addition, it is convenient to directly use the value to be converted as the benchmark for operation, but it is not easy to understand, such as

For convenience, I use s to represent hexadecimal symbols. )

(4s)*(5s * 5s)+( 1s)*(5s)+(2s)=(4s)*(34s)+(5s)+(2s)= 2 12s
