Answer:
22
Explanation:
To evaluate the expression 30 - 12÷3×2, you should follow the order of operations, also known as BIDMAS or PEMDAS:
- Brackets (B) / Parentheses (P)
- Indices (I) / Exponents (E)
- Division (D) / Division (D)
- Multiplication (M) / Multiplication (M)
- Addition (A) / Addition (A)
- Subtraction (S) / Subtraction (S)
According to BIDMAS/PEMDAS, you should perform division and multiplication before subtraction.
So, let's break it down:
1. Perform the division: 12÷3 equals 4.
2. Then, perform the multiplication: 4×2 equals 8.
3. Finally, subtract the result from 30: 30 - 8 equals 22.
So, 30 - 12÷3×2 = 22.
Hope this helps! :)
