The four operations are addition, subtraction, multiplication, and division.
Representing and solving word problems involves choosing the correct operation(s).
First, find how many donuts Rob brought to work. Since he ate 2 of the 12 he bought, subtract 2 from 12.
So, Rob brought 10 donuts to work. To find how many donuts Rob and Todd brought to work, add Rob's 10 to Todd's 6.
So, between Rob and Todd, 16 donuts were brought to work.
First, find the total number of flowers by adding the 30 roses to the 24 tulips.
So, the florist has a total of 54 flowers to use with 6 vases. To find how many flowers will be in each vase, divide 54 by 6. Use the relationship between multiplication and division.
So, there will be 9 flowers in each vase.
