If it were not true, it would not have become the rule!
The rule is to evaluate terms according the following order of priority: In UK it is BIDMAS, an acronym for Brackets, Index, Division, Multiplication, Addition and Subtraction. In US, it is PEMDAS = Parentheses, Exponent, Multiplication, Division, Addition and Subtraction order of the mathematical order of operations." Note, that multiplication and division have the same priority; also, addition and subtraction have the same priority.
PEMDAS RULE IS parentheses,exponent,multiplication,division,addition,subtraction
Opposite numbers rule
Because that is a rule mathematicians agreed upon many years ago.
Remember the memory reminder of BIDMAS which is the order of operations in arithmetic meaning Brackets, Indices, Division, Multiplication, Addition and Subtraction.
The rule(s) depend on whether you are looking at multiplication/division, addition or subtraction.
The precedence rule PEMDAS which is a mnemonic for Parentheses Exponentiation Multiplication Division Addition Subtraction

Follow the MDAS rule (Multiplication - Division - Addition - Subtraction). Therefore the answer is -132.

A slide rule is used for multiplication and division and it can also be used for trigonometry. It can also be used in money fields such as accounting.
How do i know????? That is the most complicated question in the whole world!

It's a positive number. Here's the rule: In multiplication and division . . . -- If both numbers have the same sign, then the result of multiplying or dividing them is positive. -- If the two numbers have different signs, then the result of multiplying or dividing them is negative.
The rule for missing numbers typically involves identifying a pattern or relationship in a sequence or set of numbers. This can include arithmetic sequences, geometric sequences, or other mathematical relationships. To find the missing number, one would analyze the existing numbers to determine the consistent operation or pattern used, such as addition, subtraction, multiplication, or division. Once the pattern is established, it can be applied to solve for the missing value.
