Right it was subtraction. So what does "without adjustment" mean?
math Did I do it right?
Use front-end estimation to find the value of the expression. I do not understand (without adjustment) 687 - 239 (without adjustment) is this right? 600 + 200= 800 + 126=926

Does (-2)^7 = -2^7
Bob, I am lost at what you mean.
I think I made a mistake in how I wrote the first one. I should have said (-2)^7 So would I be correct in saying -2^7
Please check answers
(-2)7=-2^7 -2^5 = -2*-2 = 4 * -2= -8 * -2 = 16 * -2 = -32
math Did I do it right?
That was rude and uncalled for! It asks for expanded notation.
math Did I do it right?
Calculate using expanded notation, showing steps. 72 + 806 Did I do it right? 72 + 806 (7*10) + (2*1) + (8*100) + (6*1) =(8 * 100) + (7*10) + (6*1)
