OPERATORS BLOCKS
Operators Blocks are used to do arithmetic and logical calculations. Blocks in the Operators
category are oval and hexagon in shape. These blocks are colour-coded as light green.
Arithmetic Operators
Scratch has four operators that allow you to
do arithmetic calculations. These are addition, Addition
subtraction, multiplication and division. Look at
the code to use addition block.
Similarly, you can use the other blocks to perform subtraction , multiplication
and division .
Relational Operators
Scratch has three operators that allow you to
compare the relationship between two values greater than
or variables. It will compare two numbers and
decide whether it is true or false. These are
greater than, less than and equals to.
Look at the code to use greater than block.
Similarly, you can use the other blocks to perform less than and equals to
.
Logical Operators
Using logical operators, you can combine two or more relational operators to produce a single
true/false result. These blocks allow you to further refine your comparison of values.
The result is true only if the two expressions are true
The result is true only if either of the expressions is true
The result is true only if the expression is false
