what is another way to express 36 +32
The correct answer and explanation is:
Correct Answer:
Another way to express 36 + 32 is 68 or in expanded form as (30 + 6) + (30 + 2).
Explanation (300 words):
The expression 36 + 32 is a basic addition problem. The sum of these two numbers is: 36+32=6836 + 32 = 68
However, we can express this addition in different ways using math strategies like expanded form, number bonds, or place value.
1. Expanded Form (Place Value):
We break down each number into tens and ones:
- 36 = 30 + 6
- 32 = 30 + 2
Now add: (30+6)+(30+2)(30 + 6) + (30 + 2)
Group tens and ones: (30+30)+(6+2)=60+8=68(30 + 30) + (6 + 2) = 60 + 8 = 68
This method helps students understand how numbers are built and how place value works.
2. Number Line or Count On:
Start at 36 and count up 32 steps.
You could first add 30 (which is easier):
36 + 30 = 66, then add 2 more:
66 + 2 = 68
This helps visualize addition as moving forward on a number line.
3. Friendly Numbers:
Sometimes, breaking numbers into friendlier parts helps:
- Take 36 and round 32 down to 30.
- 36 + 30 = 66
- Add back the 2 that was subtracted:
66 + 2 = 68
Why this is important:
Learning different ways to express or solve addition problems builds mental math skills, number sense, and flexible thinking in math. These skills are critical for solving more complex problems in the future.
In conclusion, while the direct answer is 68, expressing it in forms like (30 + 6) + (30 + 2) makes math more understandable and shows how numbers interact.
