Step-by-step explanation:
3+5=8
8÷8=1
Answer:
The sum of 68 and 14 = 82
The product of 56 and 65 = 3640
The difference between 78 and 24 = 54
The quotient of 648 and 13 = 49.84
65 multiplied by 45 = 2925
Find the quotient of 230 and 5, then add 47 = 93
Subtract 43 and 12, then divide by 3 = 10.33
Find the product of 681 and 23, then subtract by 4 = 15659
Add 9 to the difference of 19 and 8 = 20
Multiply the sum of 87 and 16 by 13 = 1339
Subtract 56 from the product of 58 and 42 = 2380
Add 99 to the quotient of 850 and 10 = 184
