43 - 18 = 25
The answer is 36. You have to use the order of operations. first parentheses then exponents then division or multiplication after addition or subtraction.The acronym is BODMAS = Brackets(pqrentasis), Of (exponent), Division, Multiplication, Addition, SubtractionThere are no brackets or exponents so division 25/5=5 is first.No multiplication so addition is next 5+2=7 then, finally, subtraction: 43-7=3625 divided by 5 is 5, then 5 plus 2 is 7 and 43-7 equals 36.43 - 25/5 +2. 25/5=5, 5+2=7, 43-7=36.
5/43 divided by 25/86 is the same as 5/43 times 86/25. So that's (5 X 86)/(43 X 25) = 430/1,075
43 + (16/4) = 47
4 - (-39) = 4 + 39 = 43
