3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}​
Nadya [2.5K]

Answer:

Step-by-step explanation:

Alright all we need to know is to understand our brackets

So 3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}​

3+20-5-9+4-3(1-5)

Step 2

3+20-5-9+4-3(1-5)  Simplify

18-9+4-3(1-5)

Step 3

18-9+4-3(1-5)

13-3(1-5)

13-(-12) Here is the tricky part (We aren't going to subtract because the brackets multiply the equations

So,

13+12=25

Your answer is 25
