The value of the expression, that is, 20.5 – (2 * 8.1) is 4.3
We have been given the expression 20.5 – (2 * 8.1).
To solve this problem we apply BODMAS rule, where each letter stands for
B = Bracket
O = of
D = Divide
M = multiply
A = Addition
S = Subtraction
When any equation is given where there is more than one operation, we solve them according to the BODMAS rule which tells us to solve the order of operation to be followed while solving expression in mathematics.
Now solving the expression we get,
= 20.5 – (2*8.1)
First solve the bracket expression
= 20.5 – 16.2
= 4.3
Hence the answer for the expression is 4.3
