Don't worry, there's no tricks, just use BODMAS technique. No, it's trolling you:

5 × 5 + 5 ÷ 5 − 5 5\times 5+5 \div5-5 = 25 + 1 − 5 = 25+1-5 = 21 = \boxed{\color{#D61F06}{21}}

Given expression: 5 × 5 + 5 / 5 − 5 5 \times 5 + 5 / 5 - 5 .
Applying B O D M A S BODMAS ,

⇒ [ { ( 5 × 5 ) + ( 5 / 5 ) } − 5 ] \Rightarrow [\{(5 \times 5) + (5 / 5)\} - 5 ] ⇒ 25 + 1 − 5 \Rightarrow 25 + 1 - 5 ⇒ 21 \Rightarrow \color{#0C6AC7}{ \boxed{21}}

Use BOMDAS, Brackets Over, Multiplication, Division, Addition & Subtraction.

5 x 5 + 5 ÷ 5 - 5

= 25 + 5 ÷ 5 - 5

= 25 + 1 - 5

= 26 - 5

= 21

Pretty straight forward once you understand the BOMDAS rule.
