Step-by-step explanation:
A typically addition equation is
[tex]x +y = z[/tex]
where x and y is the addends and z is the sum.
Addends both play a role in what the sum will be and they are interchangble.
A addition table have rows and columns. If we move right or down, our sum will increase. If we move left or up, our sum will decrease.
Now let answer the question.
6. If we move the up one row( which is horinzontial), our sum will decrease by 1 then if we right one column our sum will increase by 1. So this means each value will stay the same.
7. If we move up 5 rows, our sum will decrease by 5. If we move to left 3 columns, our sum will increase by 3. So all of our values will decrease by 2.
- 8. Write a 10 by 10 addition table.
- Highlight a number in any row.
- To add 5 to the number, either move right 5 columns or down 5 rows
- To subtract 9, either move left 9 columns or up 9 columns.
The number should be 4 less than you choose.
