Answer this question and write a paragraph that explains how u got it (a paragraph is 5-6 sentences)
fomenos

Answer:

5915

Step-by-step explanation:

Ok, so in 5th grade, we were taught to use PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction), to get a long question correct. It has to be in that order, so start with parentheses. Here is the whole equation simplified: 8+1465+7380-2938. Now you will go from left to right. So, you have 1473+4442. And last, simplify, 1473+4442=5915. Hopefully this helped and if it did please mark it brainliest.
