Performing Multiplication

Multiplication can be performed by using Multiplication component.

Enter the numbers you want to multiply into the Multiplication(A and B).

In this case, 10 and 6 were entered.

The result is 10 x 6 = 60, which outputs the number 60.

Multiplication can be performed even if there are multiple lists

You can multiply even if you have more than one list.

There are three numbers in each Panel.

The resulting output is the result of multiplying the numerical values between the corresponding Index numbers.

The first result is 10 x 6 = 60, the second is 5 x 11 = 55, and the third is 3 x 2.5 = 7.5.

Increasing the numbers to be multiplied

You can also increase the number of values to be multiplied.

When you zoom in like this, a mark appears.

This time, press the + mark.

A new terminal will then be added to the left side, increasing the number of pieces that can be multiplied.

Thus could be done with more than three numbers.

Multiply vectors and numbers

In addition to multiplying numerical values by other numerical values, you can also multiply vectors by numerical values.

This allows you to move a vector by a numerical value in the direction of the vector, for example.

In this case, by multiplying the vector information obtained from the surface information in Evaluate Surface by the number 500, a line of length 500 in the direction of that vector was created in Line.

a line of length 500 in the direction of that vector was created in Line.

Then we were able to create a line of length 500 in the direction of the vector, as shown here.

Multiplication Shortcut

Multiplication has a shoot cut.

Double-click on the canvas and type * to immediately bring up Multiplication.

Thus, Multiplication has emerged.
