What is 23+41-7×398-15
1 answer:
This question is just a type of question that you honestly just need to punch into a calculator. However, if you just do a simple one-over-one addition of 23 and 41, then subtract, it gets even easier. Then, do another one-over-one but this time as subtraction when you take away the 7. Then you will do yet another one-over-one but for multiplication with your sum of your numbers after subtraction. Finally, do another one-over-one to get your final answer of 22,671. I will attach a picture of what this looks like as well as an illustrated one-over-one. Hope this helped!
