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
