How to add - SSAT Elementary Level Quantitative (Math)

First, identify which number is in the hundreds place. The hundreds place is 3 places to the left of the decimal. In this case, 3 is in the hundreds place.

If the numbers to the right of the 3 are 50 or more, then we will round it up to 4. If they are less than 50, we will leave the 3 the same. Here, we have 42, so the 3 will remain the same. The two numbers to the right become zeroes.

We round 342 down to 300. The 2 in the thousands place remains the same.

Add the ones column first then add the tens column . The sum is 125.

Damya bought a hot dog for cents and a drink for cents.

First, add the tens together. 5 tens and 3 tens make 8 tens, or 80.

Next, add the ones together. 4 ones and 5 ones make 9 ones, or 9.

. You can start at 80 and count up 9 with pictures, on your fingers, or you can just know.

Double check your answer by drawing tens and ones, then counting all tens and counting on by ones:

||||| + ||| = 8 tens.

**** + ***** = 9 ones.

Line up the numbers vertically. Add the ones place first . Keep the 4, carry the 1. Then add the 3 digits in the tens place . Keep the 8. Then add the hundreds place . The sum is 1284

To find out what number to subtract 0.7 from to get 2.8, just do the opposite - add 0.7 to 2.8.

Add up the cost of the items.

Amy will need to buy all three items.

To find the sum, you need to add. Line up all numbers vertically. Since one number has a decimal in the tenths place, be extra careful to line up the digits correctly. To help you, add a zero in the tenths place at the end of the other two numbers so that all digits line up correctly.

When adding the ones place, we get . The goes to the answer, and we need to carry the to the tens. The tens place adds up to with the extra .

The sum is .

. Take the square root of to obtain .

The least number is 1, followed by 3, then 6 and finally, 7.

Line up the two numbers and add vertically, starting with the ones place.

The correct answer is 841. We start in the ones column on the far right and add 6 and 5. This is 11 so we have to carry the tens digit (1) to the next column and being the ones digit (also a 1) down. Adding the tens column we get

so once again we carry the 1 and bring the 4 down. Next we add the hundreds column which

which we bring down. Thus the final answer is 841.

You add the number of cookies made in each day, so

To add fractions, first find a common denominator, which in this case is 4. To turn into a fraction with 4 as a denominator, multiply the numerator and denominator by 2.

Then add and to get .

All four sides of a square are equal. So you can add all the sides and you get 8 inches.
