Editing Elementary arithmetic (section)

=== Example ===
Subtracting the numbers 792 and 308, starting with the ones column, 2 is smaller than 8. Using the borrowing method, 10 is borrowed from 90, reducing 90 to 80. This changes the problem to <math>12-8</math>.

In the tens column, the difference between 80 and 0 is 80.

|{{verth|Hundreds}}  
|{{verth|'''''Tens'''''}}

|-
| || ||8||4
|}

In the hundreds column, the difference between 700 and 300 is 400.

{|style="border-collapse: collapse; border-spacing: 2px; text-align:center"
|
|{{verth|'''''Hundreds'''''}}  
|{{verth|Tens}}
|{{verth|Ones}}

| ||4||8||4
|}

The result:

<math display="block">792 - 308 = 484</math>
