The answer is 25?

-140,   such as headgear=30, quiver of arrows=5, crossed hactchets=10 therefore by the "order of operations"   1.Parentheses 2. Exponents 3. Multiplication  4. Division  5. Addition    6.subtraction 

For example, in mathematics and most computer languages, multiplication is granted a higher precedence than addition.[1] Thus, the expression 10 - 30 x 5 is interpreted to have the value -140, not -100. These conventions exist to eliminate ambiguity while allowing notation to be as brief as possible. Where it is desired to override the precedence conventions, or even simply to emphasize them, parentheses ( ) (sometimes replaced by brackets [ ] or braces { } for readability) can indicate an alternate order or reinforce the default order to avoid confusion. Thus the preceding expression could be changed to (10 - 30) × 5 to produce -100, or 10 - (30× 5) to produce -140 (the default interpretation if there are no parentheses).

-140

-100
