Example Questions

Example Question #5053 : Algebra Ii

Multiply:  \(\displaystyle 536\times 419\)

Possible Answers:

\(\displaystyle 224584\)

\(\displaystyle 223484\)

\(\displaystyle 223684\)

\(\displaystyle \textup{The answer is not given.}\)

\(\displaystyle 213584\)

Correct answer:

\(\displaystyle 224584\)

Explanation:

Multiply the first number with the ones digit of the second number.

\(\displaystyle 536\times 9 = 4824\)

Save this value.

Multiply the first number with the tens digit of the second number.

\(\displaystyle 536\times 1 =536\)

Add a zero to this number and save the value for later.

\(\displaystyle 5360\)

Multiply the first number with the hundreds digit of the second number.

\(\displaystyle 536\times 4 = 2144\)

Add two zeros to the end of this number, and add the previously saved numbers.

\(\displaystyle 214400+5360+4824= 224584\)

The answer is:  \(\displaystyle 224584\)

Example Question #5051 : Algebra Ii

Multiply the numbers:  \(\displaystyle 198\times 73\)

Possible Answers:

\(\displaystyle 14454\)

\(\displaystyle 16354\)

\(\displaystyle 17434\)

\(\displaystyle 18944\)

\(\displaystyle 13344\)

Correct answer:

\(\displaystyle 14454\)

Explanation:

Multiply the first number given with the ones digit of 73.

\(\displaystyle 198\times 3 = 594\)

Multiply the first number given with the tens digit of 73.

\(\displaystyle 198\times 7=1386\)

Add an extra zero to the end of this number and add this with the first number.

\(\displaystyle 13860+594 = 14454\)

The answer is:  \(\displaystyle 14454\)
