Answer:
0
Step-by-step explanation:
You must substitute and use BIDMAS to solve this question: so 12-(8-5)+(12-8)-5. Brackets come before everything in the sequence so we must solve them first. 12-(3)+(4)-5. next comes addition. 12-7-5. Now that we have nothing other than the subtractions left we would just subtract in order. So 12-7= 5, then 5-5 is 0. The answer is 0.
