Explain how the subtraction operator block works in Scratch.

• The subtraction operator block adds the first input to the second input.

• The subtraction operator block in Scratch subtracts the second input from the first input.

• The subtraction operator block divides the first input by the second input.

• The subtraction operator block multiplies the two inputs together.

Can operator blocks be used for non-mathematical operations? Why or why not?

• Yes, operator blocks can be used for non-mathematical operations.

• No, operator blocks are only for mathematical operations.

• Yes, but only for string concatenation.
