## Texas Go Math Grade 6 Module 5 Answer Key Adding and Subtracting integers

**Texas Go Math Grade 6 Module 5 Are You Ready? Answer Key**

**Write an integer to represent each situation.**

Question 1.

an elevator ride down 27 stories

Answer:

First, you need to decide whether the integer is positive or negative

ride down → it would be negative

So, unknown integer is – 27 (minus is for negative and 27 is given number).

Question 2.

a $ 700 profit

Answer:

First, you need to decide whether the integer is positive or negative

Profit → it would be positive

So, unknown integer is 700 (it is positive 700 is given number).

Question 3.

46 degrees below zero

Answer:

First, you need to decide whether the integer is positive or negative

below zero → it would be negative

So, unknown integer is – 46 (minus is for negative and 46 is given number).

Question 4.

a gain of 12 yards

Answer:

First, you need to decide whether the integer is positive or negative

gain → it would be positive.

So, unknown integer is 12 (it is positive and 12 is given number).

**Find the sum or difference.**

Question 5.

Answer:

First, add ones:

3 + 8 = 11

Now, 11 ones equals 1 ten plus 1.

Then, add tens:

8 + 7 + 1 = 16

Now, 16 tens equals 1 hundred plus 6 tens.

Then, add hundreds:

1 + 0 + 1 = 2 (last 1 is hundred from adding tens)

Finally, write 2 for hundreds:

Final result is 261.

First add ones, then tens and then hundreds Result is 261.

Question 6.

Answer:

First, Subtract ones.

Note that 7 < 8, so regroup 1 ten as 10 ones

7 ones + 10 ones = 17 ones (and 6 tens left)

Now, 17 – 8 = 9

Then, Subtract tens.

Note that 6 < 8, so regroup 1 hundred as 10 tens.

6 ones + 10 ones = 16 ones

Now, 16 – 8 = 8:

Then, subtract hundreds. Because 5 > 2 only subtract them:

5 – 2 = 3

Finally:

Final result is 389.

First add ones, then tens and then hundreds Result is 389.

Question 7.

Answer:

First, add ones:

8 + 2 = 10

Now, 10 ones equals 1 ten plus 0.

Then, add tens:

8 + 0 + 1 = 0 (1 is ten from adding ones)

Now, write 9 for tens.

Then, add hundreds:

1 + 9 = 10

Now, 10 hundreds equals 1 thousand plus 0 hundred

Finally, add thousand:

1 + 0 + 1 = 2 (1 is thousand from adding hundreds)

Now, write 2 for thousand:

Final result is 2090.

First add ones, then tens, then hundreds and finally thousands Result is 2090.

Question 8.

Answer:

First, Subtract ones. Because 7 > 5 only subtract them:

7 – 5 = 2

Now:

Then, subtract tens

Note that 4 < 8, so regroup 1 hundred as 10 tens

4 ones + 10 ones = 14 ones (and 5 hundreds left)

Now, 14 – 8 = 6:

Then, subtract hundreds.

Note that 5 < 8, so regroup 1 thousand as 10 hundreds.

5 hundreds + 10 hundreds = 15 hundreds (and 1 thousand left)

Now, 15 – 8 = 7

First, subtract thousands:

1 – 1 = 0

Now:

Final result is 762.

First subtract ones, then tens, then hundreds and then thousands.

Regroup if necessary. Result is 762.

Question 1.

The ____________________ of a number gives its distance from zero.

Answer:

Correct answer is “absolute value”

This is because:

|4| = 4, which is its distance from 0.

|- 9| = 9, which is its distance from 0.

Question 2.

The sum of a number and its _________________ is zero.

Answer:

Correct answer is “additive inverse”

For example:

Additive inverse of 10 is – 10.

Now:

10 + (- 10) = 10 – 10 = 0
