Expression |
| the
sum of a and b; the total of a and b; or words like 'in all' or 'all
together' |
The sum of two numbers is 45. |
Add a to b to equal 45. |
a + b = 45 or
b + a = 45 |
|
a more than b; a increased by b; a in addition to b. (But be
careful: 'more than' in the question part of the problem can mean
subtract-described in next entry.) |
The sum of two numbers is equal to 45, and the larger number is 13
more than the smaller. |
Add a to b to equal 45; then substitute for b the expression a + 13. |
a + b = 45,
expanded to
a + (a + 13) = 45 |
|
How much more than a is b? or How much less than b is a? |
Ben and Kara read a total of 128 pages this weekend. If Ben read 45
pages, how many more pages than Ben did Kara read? |
Subtract Ben's total, b, from the overall total to calculate Kara's
total, k. Then subtract Ben's total from Kara's. |
k = 128 - 45
k = 83
k - b = 83 - 45
k - b = 38 |
|
the difference between a and b |
The difference between two numbers is 6. |
Subtract b from a to equal 6 |
a - b = 6 |
|
a decreased by b, or words indicating a decrease, such as spend,
lose, give away, take away, deduct, etc. |
The sum of two numbers decreased by 16 is 34. |
Subtract 16 from the sum of a and b to equal 34. |
(a + b) - 16 = 34 |
|
the product of x and y; x times y |
The product of two number is 144. The larger number is 4 times the
smaller. |
Multiply x and y to equal 144; then substitute 4 times the smaller
number for the larger number. |
xy = 144
x(4x) = 144 |
|
the word 'of ' with percents and fractions |
Lonnie spends N hours on each drawing. She estimates that she spends
a third of that time planning and another 15 percent of the time
revising her work. How much time does she spend on these two
activities? |
Multiply 1/3 times N and 0.15 times N. The add the two result to get
the time, T. |
1/3(N) + 0.15(N) = T |
|
the quotient of p and r, or words like 'per' and 'each' |
In r hours James read p pages. How many pages did he read per hour? |
Divide p by r. |
P or P/r
r |
