Introduction: Short Answer First
Short answer: Yes, the “+” sign is sometimes replaced in certain Israeli religious schools, but it is not generally avoided across Israel. The standard plus symbol is still used in mathematics education, especially in secular schools. However, in some Orthodox Jewish educational settings, modified versions of the symbol may be used to avoid resemblance to the Christian cross.
This has led to online confusion, but the reality is more limited and context-specific than many claims suggest.
Where Did This Claim Come From?
Online, a claim has circulated suggesting that Israeli schools avoid using the “+” sign in mathematics because it resembles a Christian cross. Instead, it is often said they use an “upside-down T” symbol.
This raises an interesting question:
Is this actually true, or is it an internet exaggeration?
The reality is more nuanced. Some parts are based on real educational practices—but the claim is often overstated.
The Reality: Do Israeli Schools Change the “+” Sign?
In standard education systems in Israel, the normal plus sign (+) is widely used—especially in:
- Secular schools
- Universities
- Modern textbooks
However, in some religious (Orthodox) Jewish educational settings, variations of the plus sign have historically been used.
These variations are not national policy, but rather cultural or religious adaptations in certain communities.
Why Modify the Plus Sign?
The modified plus sign, particularly in educational settings, is not an effort to reject mathematics but to avoid unintentional associations with Christianity. The choice of alternative symbols is motivated more by cultural and religious sensitivities than any inherent problem with the mathematical concept of addition itself. The decision to use modified symbols is about presenting educational content in a way that aligns with religious values and avoids potentially problematic imagery.
What Symbol Replaces the Plus Sign?
In cases where the symbol is modified, several forms have been observed:
1. The Modified Plus Sign (﬩)
In some educational materials, a stylized version is used that looks like a simplified or altered cross shape.
- Unicode reference: U+FB29 (Hebrew letter alternative form)
- Often appears more compact than the standard “+”
Example:
- Standard:
+ - Modified form:
﬩

2. T-Shaped or Reduced Cross Form
Some handwritten or printed educational materials show a version that resembles:
- A T shape
- A shortened vertical stroke
- A less symmetrical cross form
Example styles:
⊥(T-like structure)- Simplified plus without full crossing symmetry
These variations are sometimes described online as an “upside-down T,” although this is not an official mathematical symbol.
3. Standard Plus Sign (Still Common)
It is important to emphasize:
✔ The normal “+” sign is still used in Israel
✔ Especially in secular education and modern mathematics instruction
There is no nationwide replacement system.
Why Does This Practice Exist?
The reason is not mathematical—it is cultural and religious.
In some Orthodox Jewish communities:
- The cross is associated with Christianity
- Educational materials may avoid symbols resembling religious icons
- Adjustments are made out of cultural sensitivity, not legal requirement
This is part of a broader tradition of symbolic caution in religious education, not a national educational policy.
Where Else Are Cross Symbols Avoided in Israel?
Beyond mathematics, similar symbolic caution appears in some contexts:
1. Religious school materials
- Some textbooks or worksheets avoid cross-like imagery
- Modified symbols may be used in exercises
2. Orthodox educational environments
- Religious institutions may avoid decorative or symbolic crosses
- Alternative imagery is preferred in printed materials
3. Religious publications
- Christian symbols are generally not used in Jewish religious literature
- Focus is placed on Jewish symbols and themes
Important: This is about avoiding religious symbolism in specific religious contexts.
What Is NOT True (Common Online Misconceptions)
❌ “All Israeli schools avoid the plus sign”
False. Many schools use the standard “+” symbol.
❌ “Israel banned the cross symbol in math”
False. There is no national law or ban.
❌ “Every Israeli student uses an upside-down T”
False. This applies only in limited religious educational materials.
The Bigger Picture: Culture vs. Education Systems
This topic often goes viral online because it seems unusual, but it reflects a broader reality:
- Israel has both secular and religious education systems
- Religious schools may adapt symbols for cultural reasons
- Secular schools follow standard international math notation
So the truth is not a ban—it is variation within a diverse education system.
Conclusion: Separating Fact from Internet Myths
The claim that Israeli schools avoid the “+” sign is based on real practices, but it is often exaggerated online.
In reality:
- The standard plus sign is widely used in Israel
- Some religious schools use modified versions
- There is no national rule or ban
What we see here is not a rejection of mathematics symbols—but an example of how culture can influence educational presentation in specific communities.
This issue also raises broader cultural questions about symbolic caution in religious settings. For example, much like some early Christian teachings rejected symbols from pagan traditions, certain Jewish communities avoid imagery that might be associated with Christianity in order to maintain cultural and theological boundaries. Christianity’s historical rejection of paganism—especially in the context of how it shaped early Christian identity—was not about the rejection of knowledge but about purifying religious symbols to reinforce a distinct spiritual identity. In the same way, Orthodox Jewish communities modify symbols like the plus sign to preserve a clear separation from Christian iconography, not to deny the intellectual value of mathematics itself.
Overall, the situation reflects how education systems can vary based on cultural and religious values, rather than a single unified policy across an entire country.
