I think it may be the ability to get the correct/same answer (percision) to within 40 feet.
Partial products are the products obtained during the intermediate stages in order to complete a multiplication process.
Consider 68
43, we have to determine the partial products in this.
Now, 
Expanding this, we get

= 
= 2400 + 180 + 320 + 24
= 2924
Hence,
and
are the required partial products in the product of 68 and 43.
So, Option 3 and 4 are the correct answers.
Answer:
34
Step-by-step explanation:
13-(-21) = 13 + 21 = 34
Answer:
93312
Step-by-step explanation:
8% in decimal form is 0.08
Multiply the number of computers by 0.08 get the amount of increase every year.
Computers produced in 2021:
80,000 x 0.08 = 6400
80,000 + 6400 = 86400 computers
Computers produced in 2022:
86400 x 0.08 = 6912
86400 + 6912 = 93312 computers




First, write both the equations in its standard form.

Now, write the equations in form of matrix.

Then, multiply the equation towards the left by using the inverse of matrix 

The product of the matrix & its inverse will be the identity matrix.

Now, multiply the matrices that lie on the left-hand side of the equal sign.

For the 2 × 2 matrix
, the inverse matrix is ⇨
.

Do the calculations.

Multiply the matrices.

Do the arithmetics again.

Finally, extract the matrix elements x & y & write them separately.
