I guess you just do 4×3 then get get your answer if you have to show your work just do an array
so basically what you would have to do is set up your numbers. it would look something like this. 68
× 49
-------------
and would then multiply 9 by 8, 9 by 6. put it down below the line while making sure to carry the numbers if need be. then do the same with the 4 times 8, and 4 by 6.
(6,-5)
5x-6(0)=30
5x=30
5x/5= 30/5
x=6
5(0)-6y=30
-6y=30
-6y/-6=30/-6
y= -5
Given:
The expression is .
Sam's calculation is
To find:
Whether Sam's thinking correct or not.
Solution:
We have,
Therefore, Sam's thinking was incorrect.
On number first we have to move 10 units from 0 in positive direction after that negative sign means move in left direction.
But we have 2 negative signs so we need to move 6 units more on positive or right direct as shown below.
