That is not mental math :-)
is olve the expression mentally and i got 114
i solve
Mentally, there is no re grouping :-) but it's all right if you can do that. So, there's no problem with that:-) With Mental Math, use estimation, then either addition or subtraction: 60 + 50 = 110. Then 3 + 1 = 4. 110 + 4 = 114. Again, I'm saying you're good :-) Have a good night:-)
