7.4 Priority Levels of Operations
A priority level is assigned to each operator used in an operation written in motion language.
For an operation involving three or more items, specify the priority level by using ().
The priority levels of operators are shown below.
• Arithmetic Operation Example
Precautions on operations involving three items or more
For example, with the operation below,
1 + 2 is calculated first according to the priority level shown above, and then the result of 3 is multiplied by 3. The final
result of 9 is then stored in MW00100. Therefore, MW00100 = 9.

• Operation example
With this operation, 1 + 2 is calculated, and the result of 3 is stored in MW00100.
• Example of operation involving three items or more
With this operation, 2 * 3 is calculated first, and 1 is added to the result of 6. The final result of 7 is then
stored in MW00100.
Therefore, MW00100 = 7
MW00100 = 1 + 2 ∗ 3;
EXAMPLE
MW00100 = 1 + 2;
MW00100 = 1 + (2 ∗ 3);
