Answer:

[tex]\huge\boxed{\sf 3599}[/tex]

Step-by-step explanation:

= 61 × 59

You can write 61 = 60 + 1 and 59 = 60 - 1

Hence,

= ( 60 + 1 ) ( 60 - 1 )

According to the formula:

[tex](a+b)(a-b) = a^2-b^2[/tex]

= (60)² - (1)²

= 3600 - 1

= 3599

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!
