Please can you tell me if the sum of this equation is correct?
19+2x5-11=18. Am I right to use BODMAS to solve it? Thanks for your help.
BODMAS works with this, yes.

There are no brackets.
There are no orders (exponents, etc.)
There is nothing to divide.
Multiply; then add; then subtract.
18 is correct.
Yes. The answer is correct. You're right to use BODMAS.

To determine if the sum of the equation is correct, we first need to evaluate it using the BODMAS (or PEMDAS) rule. BODMAS stands for Brackets, Orders (exponents and roots), Division, Multiplication, Addition, and Subtraction. It is an order of operations used to solve mathematical expressions.
Let's apply BODMAS to evaluate the equation step by step:
1. 19 + 2 × 5 - 11 = ? (Original equation)
2. 19 + 10 - 11 = ? (Multiplication: 2 × 5 = 10)
3. 29 - 11 = ? (Addition: 19 + 10 = 29)
4. 18 = ? (Subtraction: 29 - 11 = 18)
So, after following the BODMAS rule, we can see that the left side of the equation simplifies to 18, which is the same as the right-hand side of the equation. Therefore, the sum of the equation is indeed correct.
In summary, using BODMAS was the correct approach to evaluate the equation, and the answer is 18.
