Success step english 2 ppt

Answer

There are two requirements for the unknown number:

The tens digit has to be four more than the ones digit,

and the two digits have to add up to 10. The best way

to solve the problem is to eliminate answers that don’t

meet these two requirements. Consider the second cri￾terion first. A glance at the answers shows that the dig￾its in the answers a and c do not add up to 10. They can

be eliminated. Next, consider the first requirement.

Answer b contains a tens digit that is six, not four,

more than the ones digit. Answer d has the ones digit

four more than the tens, reversing the requirement.

Therefore, e is the only number that correctly meets

the requirements.

Together

In the last lesson, you learned the definitions of several

mathematical terms. This lesson will discuss ways in

which numbers work together. You will need this

information to solve simple algebra and perform cer￾tain arithmetic functions that will be part of some

CBEST problems.

Adding and Subtracting Integers

The following sample questions are examples of the

types of problems about adding and subtracting you

may see on the CBEST. The answers are given later in

this lesson.
