Answer 2

Answer:

24.91

Step-by-step explanation:

[(15 × 2) - {21 + 35 ÷ (13 - 4 + 2)}]

Using BOADMAS rule (brackets, of, division, multiplication, addition, subtraction.)

Firstly solve brackets:

= [(15 × 2) - {21 + 35 ÷ (13 - 4 + 2)}]

= (30) - [21 + 35 ÷ (13 - 4 + 2)]

= 30 - [56 ÷ (15 - 4)]

Now, subtract 4 from 15

= 30 - [56 ÷ (11)]

Now, division

= 30 - 56/11

= 30 - 5.09

And in last subtraction:

= 30 - 5.09

= 24.91
