According to the BODMAS rule, the priority in which the operations should be done is:

Operations

Symbols

B-Bracket

()

O-Of

Of

D-Division

÷, /

M-Multiplication

×

A-Addition

+

S-Subtraction

-

 

⇒ 4.992 + 13.0032 - 11.012 = (?)3 - 51.98

Approximating the value to the nearest integer:

⇒ 52 + 132 - 112 = (?)3 - 52

⇒ 25 + 169 - 121 = (?)3 - 52

⇒ 25 + 48 + 52 = (?)3

(?)3 = 125

(?) = 5
