One possible way: Make a 10 using five 4s as follows: 4 + 4 + (4 + 4)/4 = 10 Make another two 10s using five 4s in each. Multiply these three 10s.
One example. 12*8+3+7-6 = 100 The key is finding sets of 10s
The perimeter of the box is 10s
0 to the nearest hundred, for example.
One hundred thousand.
1000000/10 = 100000
43 tens and 5 ones.
ok i get this
there are 7 tenths in 275 or 2.75 10s
Constant rate of change is is counting by 10s or and even number
